Executive Board

Message from the Chief Executive TWI’s long-term progress over the past decade has been significant. This is exemplified by an increase of 275 in staff numbers to a total of over 800, the doubling of our turnover, and the large investments in extensive new TWI facilities in Cambridge, Middlesbrough, Port Talbot and Kuala Lumpur.

In the shorter term, however, 2016 was a year of mixed fortunes. On the plus side, there were the following highlights for TWI: We exceeded our previous record in project volume for individual Industrial Member companies, driven by increased demand from the aerospace, power generation and equipment, consumables and material sectors.

We won over £18m of publicly funded orders from Horizon 2020 – the European Union’s research and innovation programme, and from Innovate UK – the UK’s innovation agency.

In the North East of the UK, TWI moved into a brand new facility in Middlesbrough; and in Cambridge we completed a large extension to specialised testing and manufacturing facilities in the Robert Jenkins building.

On the other hand, we had to work around a much-reduced demand from the oil and gas sector for our training and examination products, and we did not meet the 2016 income target from publicly funded projects because orders for these arrived around six months later than budgeted.

The overall result of these factors was that TWI Group income at £72m was below that of last year and group profit reduced somewhat but remained healthy at £4.1m.

Overall market conditions for TWI have been challenging since 2014 when a steep decrease in the price of oil caused a sharp reduction of capital investment by Member companies into upstream exploration projects. This sector had been a major source of demand for TWI’s advanced testing and engineering assessment work as well

4

as our UK and international training and certification business.

Our outlook for 2017 and beyond is cautiously optimistic. Innovative TWI manufacturing technologies – some of which are illustrated in this review – have led to business growth from the aerospace, marine, defence and construction sectors, and this has led to a more balanced distribution of income from various industry sectors, partially compensating for the loss in upstream income.

Furthermore, it has been announced that the UK government’s new industrial strategy will have innovation at its core with an increased Innovate UK budget which TWI will bid for with its industrial partners. And the launch of the large construction project at Hinkley Point C will offer significant opportunities for TWI in the civil nuclear sector.

Because the major economic trends that control demand for TWI’s offerings cannot be influenced by TWI, our corporate plans since 2015 have been aimed at consolidation, with a focus on looking proactively for, and responding to, business prospects and market development opportunities, combined with disciplined cash flow management and cost control.

These aims have been broadly achieved but challenging market conditions persist and, based on this business context and current trends, our top-level business priorities for the next three years are to: Improve TWI’s Industrial Member and customer engagement for increased business from new markets: eg manufacturing technologies for aerospace, inspection validation for power generation, and life extension services for energy sectors; but also to prepare for the future needs of the oil and gas industry which remains a key sector.

Enhance our agility and better exploit cross-group capabilities, and continue the development of technical capabilities

so as to improve the value of Industrial Membership and to maintain TWI’s trusted advisor status.

Win sufficient public sector order intake in 2017 to maintain support for our underpinning R&D work in 2018 and beyond; and improve the commercial management of projects in hand.

Generate more cash through revenueenhancing measures, effective pricing, optimised collection and ongoing cost control.

TWI’s performance during a period of challenging market circumstances has been very respectable which demonstrates resilience. Our achievements have been due to the dedication and commitment of TWI staff, and we would like to thank them sincerely for their great efforts during 2016.

We are also very grateful to our governance bodies, boards and committees for their loyalty and most helpful support and advice.

International and Regional Development

International impact Despite challenging trading conditions in 2016 demand for TWI’s products overseas remained strong with nearly half of TWI’s trading activities associated with business from overseas including Europe, North America, Southeast Asia, Middle East, India, China and Japan. TWI’s overseas subsidiaries performed well exceeding both revenue and profit expectations.

More than half the total number of new industrial member recruitments came from overseas with the majority of those coming from Europe, USA and the Far East. Of particular note was the recruitment of four new members in the Middle East.

TWI’s internationally recognised training and certification products remain in demand globally.

TWI continues to explore other opportunities to leverage its training brand to support in-country upskilling to increase local capability and reduce reliance on bought-in labour. Malaysia has imposed strict requirements (Act 520) for the competence of skilled workers operating the country’s construction industries. TWI has is working closely with Malaysian government agencies, through the provision of training and assessment, to ensure that individuals wishing to work in welding and allied disciplines are appropriately qualified. TWI continues to explore other similar opportunities with governments in the Middle East and India.

The lifting of EU sanctions early in 2016 allowed TWI to re-establish activities in Iran and to expand its offering in the Central Asia region. Iran is potentially a very important market for TWI with anticipated strong demand for TWI’s training and engineering services, as it rebuilds its aging infrastructure.

International and Regional Development

Regional development The last 12 months have seen significant developments at all three of our UK regional locations, thanks to much appreciated support from a number of local authorities and enterprise partners.

TWI Technology Centre (North East) In December 2016 we celebrated the opening of our new purpose-built TWI Technology and Training Centre. Developed in partnership with Middlesbrough Borough Council, Tees Valley Combined Authority and the Local Enterprise Partnership, the £10m purpose-built facility has been enabled through European Regional Development and Regional Growth funding along with investment from TWI. The new Centre, opened by the Rt Hon the Lord Heseltine (see page 15) represents a sizeable boost to engineering consultancy and industry training in the North East for organisations looking to improve engineering practice and safety.

TWI Technology Centre (Wales) 2016 was an important year for the development of our Port Talbot site, with the commencement of a £12m Advanced Engineering and Materials Research Institute (AEMRI) programme at Harbourside Business Park funded with an EU investment and matched by industry support. AEMRI, launched by First Minister of Wales, Carwyn Jones, is a unique facility in Wales for structural testing and evaluation, supporting cutting-edge industrial research with partners in sectors including aerospace, automotive, electronics, and nuclear and renewable energy. Notable early successes in the programme include the winning of over £1m new research contracts, the creation of 16 highly skilled jobs, and training opportunities for 20 PhD students.

Mike Russell Director, Operations

TWI Technology Centre (Yorkshire) 2016 has also seen exciting developments in our Yorkshire Technology Centre in Rotherham – specifically the construction of a new state-of-the-art laser additive manufacturing facility, with associated new equipment and staff recruitment plans. This new laboratory adds industrial standard additive manufacturing production capabilities to our already extensive research portfolio in this important area.

Corporate Social Responsibility Corporate social responsibility is at the heart of TWI’s mission. We exist to help the engineering, materials and joining communities to work together to manufacture, operate and decommission high-integrity structures. We assist our Industrial Members to address the challenges of sustainability, meeting growing demands whilst minimising use of resources and environmental impact.

The oil and gas industry faces increasing challenges to extract hydrocarbons from ever more difficult locations, whether in hot and corrosive fields deep below the sea or in the cold and remote fields of the Arctic.

TWI works for its international oil and gas Member companies, to help access these resources safely and economically, through welding engineering, materials testing and integrity management technologies.

For our transport systems Members, there is constant pressure to improve fuel efficiency and minimise environmental impact. TWI provides new joining, inspection, coating and manufacturing technologies to companies across the world, to support the manufacture of lightweight, fuel-efficient vehicles.

Power generation is undergoing a vital transition from hydrocarbons to lowcarbon technologies. The need for plant to be affordable, whilst being reliable and long-lasting, has never been greater. TWI supports the sector through manufacturing technologies for wind turbines, nuclear waste canisters and the international prototype fusion reactor, advanced inspection methods to assist life extension of plant, and remote laser cutting for decommissioning.

world in certification of competence to fabricate and inspect engineering structures.

TWI has furthermore established the Structural Integrity Research Foundation, with support from the UK Government, to train over 500 postgraduates over the next ten years at the National Structural Integrity Research Centre based in Cambridge.

Community

In 2016 TWI has been pleased to support a series of events at schools and colleges promoting the fun and practical side of engineering and its relevance in our world, as well as showcasing the different educational routes for students interested in a career in materials science and joining.

With the help of the Welding Institute’s Younger Members’ Committee, the Tipper Group comprising female engineers, and TWI STEM volunteers from its headquarters and regional offices, the outreach programme takes technology on tour including the popular Welding with Chocolate workshop and an annual interactive seminar at the Cambridge Science Festival.

In the academic year 2015-16, TWI organised or helped with over 50 events or experiences for young people. Highlights included a prize-winning Nuffield summer placement at TWI for A’ level student Alexander Lewis for which he received the Global Challenges, Manchester Solutions: Energy Prize from the University of Manchester, and an A* grade in an Extended Project Qualification for Loughborough Grammar School student Alex Cortazzi on his study into the effectiveness of electron beam welding in industry.

In addition, TWI hosted 28 educational industry tours.

In 2016, among its charity and community contributions were a Diving for the Disabled event at TWI’s Kuala Lumpur base in South East Asia, formalisation of provision for the Bateman’s Trust project in Chennai, India and in the UK, support for a Cambridgeshire school to achieve its Primary Science Quality Mark.

Environment

TWI’s existing certification of its ISO 14001 Environmental Management System was maintained during 2016 with no major nonconformances. It is intended to transition to the revised standard (ISO 14001:2015) by the end of 2017, ahead of the required deadline of August 2018. An audit of TWI’s ESOS (Energy Saving Opportunities Scheme) compliance was conducted by the Environment Agency with no non-conformances raised.

Whilst we all strive to avoid engineering failures, occasional instances do occur. TWI is an expert of resource in the understanding of structural failure, working with our Members to diagnose the causes of failure, find immediate solutions and develop underpinning technologies to minimise future risks.

The world needs more competent people to rise to these challenges. TWI’s training schools operate worldwide and lead the

Total welding support for tanker-FPSO conversion TWI served as the technical welding authority in a two-year conversion of a crude oil tanker to a floating production storage and offloading vessel (FPSO).

The OOGTK Libra Gmbh & Co KG joint venture oversaw the conversion of a 73,000 ton crude oil tanker built in 1995 as the Navion Norvegia to a fully equipped FPSO, the Pioneiro de Libra.

TWI’s expertise as a technical welding authority and international reputation in the oil and gas industry meant the organisation was drafted in to provide technical support throughout the two-year project across four shipyards in South East Asia. The conversion process was completed early in 2017.

With over 250 welding procedures to assess, TWI ensured the welding procedures were correctly qualified, in accordance with

26

varying welding standards and codes and internal specifications, giving OOGTK regular updates. Its audit of the four shipyards, spread across three countries ensured the different subcontractors were all following sound working practices. TWI also worked to oversee inspection of critical areas using phased array ultrasonic and eddy current testing, advising on specific inspection procedures and assessing results. TWI also deployed experienced welding engineers to support the attachment of the FPSO turret head and assess the risk of distortion.

it will be the first vessel to produce oil from this area. Capable of working in depths up to 2400m, the FPSO can produce up to 50,000 barrels of oil per day and is expected to remain in service for the next 12 years.

For OOGTK, TWI’s involvement meant the company had access to top-tier technical support on any issues relating to welding, inspection, corrosion and distortion.

The FPSO Pioneiro de Libra will operate off the coast of Brazil, in the Libra pre-salt area of the Santos Basin. As its name suggests

Failure along spiral welds in a gas pipeline TWI has worked with the Kuwait Oil Corporation (KOC) to find the root cause of failure in a critical high-pressure wet sour service gas pipeline in West Kuwait.

The pipeline had suffered several leaks and the most recent was due to a crack along a spiral weld. During repairs the pipeline was found with severe internal corrosion leading to the pipeline being decommissioned. After inconclusive in-house investigation and testing, KOC contacted TWI to conduct a failure investigation, which included extensive examination and testing of the failed pipe and detailed analyses.

TWI experts noted that the pipe material had been correctly selected for wet sour service and externally the pipeline was in good condition, indicating an effective coating and cathodic protection system during service.

Visual inspection of pipe samples showed severe internal pitting in the bottom of the pipe in the 4-8 o’clock position, with a spiral weld failure in the same area. Phased array UT confirmed that the crack was longer on the inside than on the outside revealing that the cracking originated internally.

TWI found that the pipeline had suffered from extensive internal corrosion caused by the presence of water, CO2 and H2S gases, suggesting that the dehydration plant, which was the main source of internal corrosion mitigation in this pipeline, was not functioning adequately. The team also found that a slight weld mis-alignment had resulted in a slight roof topping of the spiral weld.

This will have increased in-service stresses in these regions and a mis-alignment of the spiral weld would cause higher local tensile stress when under pressure. In addition, regular pipeline shutdowns would have added a small amount of cyclic loading.

Following the investigation TWI concluded that none of these factors were particularly severe on their own, however, when combined, the effect could be significant.

The probable cause of cracking was a combination of increased localised stress at the spiral weld in combination with corrosion due to a severe sour service environment.

Eventually the local stress increased to such an extent at the spiral weld that cracking occurred.

Following the results of this investigation KOC replaced the pipeline with a seamless sour service pipe rated to the current level of H2S and water cut.

Investigation into high-grade mooring chain fatigue resistance TWI is working with Industrial Members from the offshore oil and gas sector in a joint industry project (JIP) to investigate fatigue in mooring chains. Demand from industry has stimulated the need for test data generated under realistic conditions to gain a detailed understanding of the factors affecting fatigue performance.

Mooring chains are used for deep water oil and gas developments, for mooring floating production storage and offloading vessels, buoys and spars. Larger links and higher strength materials such as R5 grade are being considered, as they can offer higher static strength. The performance of higher steel grade and large diameter chain is not well understood however, it is possible that the increased static strength may not result in improved fatigue performance in seawater.

Existing fatigue design recommendations are

based mainly on data obtained in the 1990s, on chains with relatively small diameter (mainly 76mm) and low steel grades (R3 and R4). Now TWI will provide updated independent data for higher chain grades (R5) and larger diameters (127mm) with fullscale fatigue tests in seawater.

The TWI team has designed and manufactured a test rig to provide full-scale fatigue endurance data for mooring chains in seawater. The project started in 2012 is expected to be completed in January 2018. This JIP will critically review existing knowledge, and provide data for highstrength steel, and a larger link diameter. It will establish the primary material properties affecting performance, and provide independent data for higher chain grades and larger diameters. Furthermore, this JIP is also trying to investigate the failure mechanism, to determine whether crack initiation or crack

propagation is dominant in total fatigue life.

TWI is working with American Bureau of Shipping (ABS), BP Exploration Operating Co Ltd, Shell Projects and Technology and Statoil Petroleum Co Ltd to improve safety, reliability and reduce costs.

Dissimilar Metal Interfaces and Resistance to Subsea Hydrogen Cracking Following a number of in-service failures, TWI identified significant interest in understanding the microstructures and environmental conditions that contribute to hydrogen cracking of subsea dissimilar metal welds. Through a programme of environmental performance tests under cathodic protection, the environmental performance of F22 and 8630M-Alloy 625 interfaces was evaluated, using high resolution scanning and transmission electron microscopy to determine the microstructures responsible for the observed environmental performance.

The key findings were:

The resistance to hydrogen cracking of dissimilar metals welds may be optimised by balancing competition between heat-affected zone tempering and new phase formation Optimal post-weld heat treatment times were found to be below those which led to the precipitation of carbides within a narrow band adjacent to the fusion line Cracks found in a retrieved dissimilar joint indicate subsurface initiation, secondary crack coalescence and progressive propagation.

It has previously been suggested to industry that low alloy steel butterings could be used as an alternative to Alloy 625 for dissimilar joints, to avoid issues with carbon diffusion, and hence avoid the formation of hard zones within the nickel. However, an austenitic closure weld would still be needed, introducing an as-welded dissimilar interface. This research has shown that the relationship between post-weld heat treatment and mechanical properties (particularly in the presence of hydrogen) is more complex than was thought. Operators wishing to use such new joint designs should therefore carry out tests to assess the safety of the design, and, if conventional nickel alloy buttered joints are used, a thorough analysis of the effect of post-weld heat treatment should be carried out. The importance of the service temperature on resistance to hydrogen cracking is also highlighted.

This research will make a significant contribution to cost reduction (through improved designs and more reliable operation) and safety for the subsea oil and gas sector.

Reducing the costs of offshore wind TWI is actively engaging with industry stakeholders, including wind farm developers, foundation fabricators and coating suppliers to initiate the development of novel corrosion protection solutions based on thermally sprayed aluminium (TSA) that have the potential to reduce the cost of offshore wind.

TWI has established itself as a world leader in the understanding and application of metallised coatings for the corrosion protection of offshore structures, having run a number of joint industry projects, primarily on behalf of TWI’s oil and gas sector members. TSA is used extensively in the oil and gas industry on offshore platforms and in pipeline applications, and TWI now has a wealth of industrially relevant knowledge on the performance of such coatings that it is bringing to the renewable energy sector.

Offshore wind is growing at an extraordinary pace, with industry reports estimating that over the past five years an offshore wind foundation has been installed every 40

hours. In 2016 alone, 338 new turbines were grid-connected in Europe and â‚Ź18.2bn worth of projects reached a final investment decision. With the technology and the market maturing, the cost of offshore wind is steadily decreasing and may soon draw level with conventional power generation.

Replacing conventional corrosion protection, based on paint and sacrificial anodes, with a single coating of TSA provides a high reliability coating that requires less frequent maintenance and repair and reduces the cost of manufacturing foundations.

While often seen as an expensive coating option, TSA can offer significant savings during fabrication as there is no need for sacrificial anodes, secondary steelwork, or extended curing times for multiple coatings of paint. Despite the potential cost savings offered through the use of TSA, to date, the offshore wind sector has been reluctant to implement new coatings due to uncertainties surrounding performance in certain settings, unique to offshore wind foundations.

Thermally sprayed aluminium application in progress

TWI is currently working with a consortium of stakeholders in the offshore wind sector and has been awarded a ÂŁ1.2m project by Innovate UK to address the barriers to the adoption of TSA and introduce a potentially radical new corrosion protection design into the industry.

Thermally sprayed aluminium lightning protection for composite aircraft TWI has been working with AVIC Composites Corporation (ACC) to develop a Lightning Strike Protection (LSP) system for composite aircraft.

ACC approached TWI as it has significant experience in developing thermal spray aluminium (TSA) coating technology for the protection of polymer composite aerospace structures from lightning strike. TWI has developed a well-defined thermal spray coating procedure for application of LSP coating systems for carbon-fibre reinforced polymer (CFRP) aircraft for ACC. In the project, TWI compared the ACC and LSP systems and validated the TWI procedures for application onto ACC carbon fibre reinforced polymer used in commercial aircraft manufacture.

The work involved studying the effects of process parameters on coating performance

32

on carbon reinforced polymer, including surface preparation, process/target efficiency, coating microstructure, roughness, oxygen content, adhesion and thermal shock resistance. The lightning strike performance was also evaluated.

The TWI project team identified the process parameters that have the greatest influence on key coating characteristics and provided ACC with a well-defined thermal spray coating procedure for application of LSP coating systems for CFRP aircraft.

On completion of these trials ACC installed a three-stage automated facility, comprising grit blasting, thermal spraying and painting for the application of coatings on composites for lightning strike management capability and work continues to move the process up the technology readiness level scale for manufacturing.

Wire-Fed Electron Beam Additive Manufacture Wire-fed electron beam additive manufacturing (W-EBAM) has the potential to offer high build rates compared with powder-based techniques, and cost savings compared with machining, particularly for high-cost materials. However, distortion has been a concern. TWI has carried out research to demonstrate the ability of W-EBAM to build structures using Ti 6Al 4V, an alloy widely used in aerospace, and to fabricate a demonstrator part, including a cost comparison.

This required the development and validation of finite element models of the process, in order to predict the impact on residual stress and distortion of changes to manufacturing settings, such as electron beam parameters, deposition rates and deposition patterns/ sequences.

The models were also used to assess the effect of three residual stress mitigation techniques: pre-heating, pre-tensioning, and the use of a heat sink.

Pre-heating provided the greatest benefit, with a reduction of up to 45 per cent in distortion predicted. Pre-tensioning was investigated by heating a band of material on the back side of the plate, opposite the region of the deposit layers, but gave less benefit that pre-heating. Simulation of the use of a heat sink offered much smaller benefits than either pre-heating or pretensioning, and was not investigated further.

The processing parameters and distortion mitigation measures found to offer the greatest reduction in part distortion were then implemented to fabricate a wing rib post demonstrator part from Ti 6Al 4V. This fabrication was successful and showed the controlled distortion expected.

Fully machined wing rib post demonstrator component W-EBAM therefore offers potential for significant cost savings, and should be considered, alongside other additive manufacturing processes, for selected components fabricated from high-cost materials.

For a basic titanium aerospace component, such as this, a 40 percent reduction in cost is estimated, compared with machining from solid.

Alex Robelou, TWI, Andrew Norman, ESA, Renato Bellarosa, Airbus D&S and Naveed Iqbal, TWI discuss the low cost titanium propellant tank manufactured at TWI

Friction stir welding for low-cost titanium propellant tanks TWI has been working with astrospace contractor Airbus Defence and Space to satisfy a European Space Agency (ESA) request to investigate cost-effective manufacturing methods for titanium propellant tanks.

The project investigated the feasibility of using stationary shoulder friction stir welding (SSFSW) techniques for the cylindrical welding of titanium alloys suitable for launch vehicle propellant tanks. Reducing lead times and costs by developing and validating the system required to weld titanium alloys and also to raise the Technology Readiness Level (TRL) of SSFSW of titanium alloys to prototype demonstrator (TRL6).

Current manufacturing methods for titanium propellant tanks suffer from extremely high cost and long manufacturing lead times.

Material wastage from complicated forging,

34

machining, and forming techniques coupled with electron beam (EB) welding makes propellant tanks one of the most expensive hardware items on a satellite launch programme.

FSW is capable of welding high strength high temperature materials such as steel and nickel alloys and, by using a modified version of FSW called Stationary Shoulder Friction Stir Welding (SSFSW), titanium can also be welded successfully.

The TWI team conducted an extensive review of material and manufacturing processes, with forged and cast titanium both offering the mechanical property requirement. In August 2016 TWI successfully performed the world’s first full circumferential SSFSW of two 420mm cast titanium cylinders. The test pieces were then subjected to full NDT evaluation and mechanical assessment to

confirm joint quality and properties.

In winter 2016 TWI fabricated and delivered the first one of four SSFSW cast titanium prototype demonstrator (TRL6) propellant tanks to the European Space Agency, with a delighted response from ESA. The achievement and success of the ESATWI-Airbus team was later recognised in March 2017 when they were awarded the Raiser 2017 Award for Friction Welding Innovation.

Ultrafine austenitic stainless steel as a lightweight automotive material The use of high strength steels within car body structures is rapidly growing to meet the requirements for increased vehicle safety and fuel efficiency, through light-weighting of structures. In particular low carbon advanced high strength steel grades (AHSS) are currently being applied by the steel community.

These grades include; dual phase, complexphase, martensitic, and transformationinduced plasticity. These first and second generation AHSS grades meet the performance demands of specific parts, with unique microstructural features, alloying additions, processing requirements, advantages and challenges associated with their use.

TWI is working with partners from across Europe in a study into the development of new stainless steel grades specifically

36

for the automotive sector. The increase in industry demand has stimulated research for the development of steels with improved strength-ductility combinations, with the added advantage of not requiring zinc coating for corrosion protection.

ULTRASLIM is a European project under the RFCS Programme coordinated by Centro Ricerche Fiat (CRF) and with the participation of Acerinox, TWI and Tecnalia.

ULTRASLIM addresses this research field through the development of new austenitic stainless steels that can be used in a wider range of applications. The joint project aims to deliver a new grade of austenitic steel that is able to meet the requirements of the automotive sector, specifically with a strength and ductility outside the range of present AHSS materials. This should be realised in combination with low production costs and excellent corrosion performance. The project aims to release its findings in late 2019.

Repairing worn shafts using laser metal deposition TWI has carried out an extensive programme for an Industrial Member on applying laser metal deposition (LMD) to both new and worn shafts from industrial rotating equipment.

The Member contacted TWI to carry out repairs to the worn shafts, and after assessing the repair, identified laser metal deposition as the most appropriate process to return the shafts to service. The LMD process conducts much less heat into the substrate material than many conventional techniques creating a fine microstructure with low levels of dilution between layers and low distortion. Due to the exceptional clad the laser deposition process provides, the member introduced the process to new shafts. TWI has been developing the laser metal process for the last decade exploring its use for everything from repair of highvalue parts to fabrication of large freeform components, in a number of industries.

with process parameters, and following this TWI produced a welding procedure specification for the client’s approval. Using a Trumpf DMD505 system deposition material was added to two worn shafts using the approved weld procedure developed by using the deposit geometry supplied by the client, to give a new surface suitable for postdeposition machining.

TWI was able to procure, install and commission the right equipment to the client’s satisfaction and subsequently combine the laser deposition system, its parameters and surface preparation procedures to meet the client’s acceptance criteria, with the technical ability acquired from extensive experience gained from previous laser metal deposition projects.

Laser cladding worn rotating shafts

LMD is an additive manufacturing process that uses a laser beam as an energy source focused on a substrate through a nozzle to create a melt pool. Metal powder or wire is then added to the melt pool. The melted particles fuse and solidify while the nozzle is manipulated around the substrate to form a new layer of the component. Fabrication and repairs in titanium, nickel, aluminium, steel and cobalt can be made with reduced material wastage, and reduced tooling costs, the process benefits from a large working envelope, and near net capabilities, it also produces functionally graded parts, and fully customised parts to suit individual requirements.

TWI assessed the worn shafts and selected LMD as the best repair process, setting immediate objectives to procure install and commission additional equipment to the client’s satisfaction, and produce two cladded test pieces for analysis using agreed deposit geometry from the client’s plan. One shaft was supplied specifically for experimenting

TWI delivers full friction stir welding support for formwork specialist MFE Formwork, based in Malaysia, adopted friction stir welding (FSW) to boost orders of aluminium formwork for concrete, allowing the company to increase its production rate by 50 per cent. MFE worked closely with TWI when adopting FSW in 2011, and got in touch again when it decided to move its formwork manufacturing over entirely to FSW. TWI put together a three-stage work programme in 2016, comprising a procedure development study at TWI UK, on-site training in Malaysia and machine testing and commissioning in Taiwan.

With the panels in 24-hour production, MFE worked with TWI to identify optimal welding conditions for a high welding speed. The TWI team travelled to MFE’s head office in Malaysia, en route to Taiwan, to train staff and test the existing FSW production line.

Thirteen staff completed the one-day TWI Foundation Award in Friction Stir Welding

38

(delivered in Bahasa Malaysia, the national language). TWI specialists also reviewed the existing FSW formwork production ensuring it was meeting welding specifications, conducting welding trials using the newly qualified welding staff, and assessed welds using visual inspection and mechanical testing.

To support the extra FSW work, MFE commissioned a new prototype FSW machine from the Taiwanese manufacturer.

TWI assessed the system’s capabilities with on-site factory acceptance tests in Taiwan on behalf of MFE, and tested the formwork welds to match the standards required by MFE. The prototype machine was found to produce even less distortion than the original test demonstrators, as the larger machine bed of the new machine was more effective at dissipating heat. MFE have now ordered seven of the machines to increase

the production rate of the existing FSW production line.

By assisting MFE Formworks with every aspect of FSW implementation TWI was able to ensure the Member will remain competitive by efficiently producing reliable products, and continue the growth of its business.

Guided Wave Inspection of Panels and Plates Structures made of plate-like components are common in a variety of industries where the environmental, social and economic impacts of failure due to cracking or corrosion may be severe. In many cases, these structures are only partially accessible and are difficult to inspect frequently. Guided wave inspection has potential to inspect large areas via access from a single point, typically using an array of transducers to generate the required ultrasonic pulse. For example, a collar of transducers is used for inspection of pipes and other cylindrical structures in Plant Integrity’s current Teletest products.

TWI has developed and successfully tested prototype transducer arrays for the inspection of panels and plate-like structures, one array capable of producing an omnidirectional guided wave, and one capable of producing a unidirectional guided wave. This required the initial development of a software tool – linear superposition analysis (LSA) – to allow rapid screening of potential designs. Conventional finite element analysis would take too long to investigate all the required variations, but was used to validate selected simulations.

Prototype omni-directional guided wave transducer Working to constraints imposed by the individual transducer elements, an octagonal array was selected as the best design for an omnidirectional transducer, and a two-row linear array for a unidirectional transducer.

Simulations indicated that these would give the required level of directionality and intensity of the desired guided wave mode.

Prototypes validated these predictions, and were then assessed in simulated applications. The omnidirectional array was capable of detecting a simulated crack in a 4m x 2m x 10mm plate. The unidirectional

array was capable of detecting thinning due to corrosion in the 1.5m high web of an I beam forming part of a railway bridge, with ballast still in contact with the web.

Development of guided wave transducers with bespoke directional properties opens up a variety of potential applications in nondestructive evaluation and condition and structural monitoring. The prototypes show great promise and will be assessed in a range of new applications.

Dissimilar laser welding of aluminium and copper alloys for electrical connections TWI worked for its Members to solve the technical problems of joining aluminium to copper using laser welding technology. An increasing number of enquiries over the past two years from Members asking for support in this area led to the successful development of a high-speed laser technology-based solution.

An increase in manufacturing demand in the automotive industry for example, for products with high capacity battery cells is leading an interest in the technical solutions. High capacity battery cells use aluminium and copper, as the anode and cathode terminals respectively, to improve electric current flow and boost a vehicle’s performance. Existing electrical connection joining technologies, such as ultrasonic welding and the use of direct conductive adhesives are deemed too slow for the high demand in a manufacturing situation.

40

Laser welding is considered an attractive process to industry due to its high processing speed and highly repeatable, fully automated process. However, laser welding of copper to aluminium presents several challenges.

Because of the high surface reflectivity and thermal conductivity of copper, and the poor miscibility of aluminium and copper, keyhole instability and brittle intermetallic formation are common issues found when laser welding these metals.

TWI identified a successful laser technologybased approach to address the technical challenges, and developed a high speed (up to 20 m/min) laser welding technique that uses a high brightness laser and a narrow beam width. The project team demonstrated successful welds in range of material thicknesses, ranging from 0.2mm up to 1mm.

The team then micro analysed the welds in-house with positive results showing that a high speed laser welding approach was capable of minimising the formation of the brittle intermetallic phases, and improving the electrical performance of the dissimilar joints.

Ultrasonic welding enables design excellence for thermoplastic nebulizer TWI worked with Member company and health technology specialist Philips Avent to conduct a feasibility assessment of welding individual component parts of a new nebulizer device. Many of the individual component parts to be welded had complex curvature, so assessment was needed before manufacturing. The combined efforts of TWI and Philips Avent led to a nebulizer being available for children and adults needing respiratory treatment.

The Innospire Go is an award-winning portable mesh nebulizer, with a simple twopiece design with a detachable mouthpiece making the device simple to use, clean and maintain, and it is particularly relevant for children who find older systems more difficult to use. Innospire Go, has recently won an ‘iF’ Design Excellence Award from iF World Design Guide and is now in full production.

As many of the nebulizer’s individual component parts have a technically challenging complex curvature, the team carried out a feasibility study to assess the best method for joining. TWI identified ultrasonic welding as the most appropriate as it produces high quality joints rapidly in a range of materials and joint configurations.

It is a relatively mature process which is commercially accessible, meaning development and production costs should be lower.

with ultrasonic welding trials conducted on 100 pairs of each material supplied by Philips Avent, using a range of machine settings.

On completion of these trials the team assessed a number of the welds by manual testing and visual inspection and found that the robustness of the device was acceptable.

TWI provided a summary of the work, which included the feasibility of ultrasonic welding each joint, and suggestions for process improvements.

TWI assisted with the design and manufacture of the aluminium sonotrodes and nests, components that are responsible for introducing the workpiece to the 20kHz ultrasound energy.

Non-destructive testing TWI technology fellow Ian Cooper chairs the British Institute of Non-Destructive Testing Technical Committee and is a member of the Aerospace and Composites committees.

These committees have established a number of working groups and user groups aimed at fostering the development of new and emerging NDT technologies with a view to informing and encouraging the production of user guides and standards.

He is also vice chair of the ACE/61/-005 and ADS NDT Special Interest Group, which seeks to represent the interests of British aerospace companies through interaction with legislative bodies such as CAA, UKNDTB and Nadcap. Working groups have produced recommended practices for controlling the use of LED UV light sources, and provided input to the generation of digital radiography Nadcap audit checklists as well as providing input to international standards bodies. TWI also chairs a group preparing a standard for carrying out EMF exposure assessments.

Nuclear TWI supports a range of activities relating to the AFCEN RCC-M and RCC-MRx codes by bringing expertise to code sub-committees in term of welding technology, non-destructive testing and mechanical testing. These codes relate to the design and construction of components for nuclear islands and hightemperature components. Since 2013, we have been chairing a UK user group of major UK companies involved in manufacturing nuclear components for new EPR projects, assisting UK nuclear supply chain businesses in using the RCC-M code effectively, and facilitating training, supply chain capability, code requirements and knowledge exchange.

In summary, our standards contributions are shaped by constant interaction with our Members and reflect current opinion from a wide range of organisations in all industry sectors

Training and Examinations

Training and examinations TWI has increased its portfolio of Virtual Academy products, adding resources for Senior Welding Inspector and conventional ultraosonic testing and advanced time-of-flight-diffraction (ToFD) non-destructive testing (NDT) techniques to the list of available eLearning resources. eLearning is now available in a variety of options, for NDT and Welding Inspection courses, including pre-learning, refresher, appreciation and blended (part eLearning, part classroom) formats.

Chris Peters – Global Manager Operational Support

Jim Kerins – Regional Manager India, Middle East and Africa

Blended learning gives students the chance to learn in their own time and at their own pace. It is also beneficial in helping reduce the impact of training on industry by limiting time away from the workplace. It is estimated that TWI has saved industry over 20 man months of time away from the workplace by offering NDT courses as a blended option.

20

man months saved through eLearning Blended learning courses have also proved popular overseas with several courses being run in Canada and in Spain where the eLearning materials and lectures were both delivered in Spanish.

Students have been very positive about the benefits of eLearning and TWI lecturers have also commented that students are better prepared, asking more informed questions during the classroom sessions.

TWI is constantly seeking ways to improve its training courses and has introduced new scenario-based learning and assessment within the senior welding inspector course.

The scenario approach requires students to use a combination of standards and specifications together with knowledge gained from the course to make accept/reject decisions. The scenario approach truly tests the inspector’s ability to use a combination of knowledge and lateral thought to solve real-life problems.

Regions TWI South East Asia consolidated the opening of its new facilities in Shah Alam near Kuala Lumpur by hosting more than 250 visitors from various sectors of industry for a TWI Technology Day. This was an opportunity for TWI SEA to present its capabilities in the region, create links between companies, and bring industry closer together.

The technical programme included advanced non-destructive testing and welding, with practical demonstrations on the latest developments in automated welding and wet welding, and displays featuring painting and coating equipment.

TWI South East Asia showed its support for the development of young Malaysian welders by training the gold medal winning Malaysian welding team for a young people’s skills competition.

The 11th Asian Skills Competition 2016, held in Kuala Lumper September 2016, saw ten countries including Brunei, Cambodia, Indonesia, Laos, Malaysia, Myanmar, Philippines, Singapore, Thailand, and Vietnam compete.

TWI South East Asia is backing the Malaysia team to go for gold at the ‘Olympics’ of skills competitions, The World Skills Competition which will be held in Abu Dhabi in October 2017.

The Central Asia region received a boost in 2016 when EU sanctions on Iran were lifted and TWI was able to re-establish its training activities out of Tehran. This is an important market for TWI with potential for high demand for TWI’s training and certification.

For some time now there has been interest in exploring the markets in Russia however EU sanctions restrict certain training. TWI has successfully applied and been granted licences to allow it to deliver welding inspector and diver training in Russia.

In the Middle-east TWI continues to explore opportunities to support local upskilling initiatives. Business in Saudi Arabia has improved after changing the structure of agent support in the region.

The winning welding team trained and guided by TWI’s Malaysianbased welding instructors who helped contribute to Malaysia’s impressive winning haul of twenty four gold, four silver, five bronze medals and six medallions of excellence.

Fernando Antonio Juliao Martins undertaking his PAUT training at TWI

Brazilian student takes advantage of blended learning option for ultrasonic training A training candidate based in Brazil used TWI’s eLearning service to maximise his chances of successfully achieving CSWIP certification – with brilliant results.

Fernando Antonio Juliao Martins from Rio de Janeiro has been working as an ultrasonic inspector for five years, primarily in the oil and gas and power sectors. With these industries increasingly demanding more advanced non-destructive testing methods, he decided the next step in his career would be to undertake training in phased array ultrasonic testing.

Based on research and recommendations from his colleagues, along with TWI’s unrivalled reputation for delivering industryleading training, Fernando decided to travel to the UK to attend a course at the newly built training school at TWI’s Great Abington headquarters.

50

The course he enrolled on was Phased Array Ultrasonic Testing (PAUT).

Travelling from South America to Europe for training is a serious commitment of both time and money. Self-sponsored student Fernando was determined to do everything he could to ensure he passed his CSWIP exam first time, so when registering for the course he opted for the blended learning option, combining online study with traditional classroomdelivered tuition.

This had a number of advantages. First, it meant that he was only required to attend two weeks of training in Great Abington, rather than three – the first week’s material was covered online. This meant less time away from work in Brazil and a considerable saving in accommodation costs.

Second, it gave him flexibility to study the online segment at a convenient time.

Fernando was able to accommodate this around his full-time working commitments, studying online in the evenings.

Studying online is especially beneficial to someone, like Fernando, whose first language is not English. He was able to revisit sections of the course to make sure he understood them, with clear supporting videos helping to explain some of the more difficult concepts. With 60 days’ access to the materials included with the course, he had plenty of time to make sure he had a good understanding of every topic.

Fernando was very impressed with his time at TWI. Praising the facilities as being like ‘a different world’ and highly complimentary of the training and support staff, he plans to return in the future to gain CSWIP certification in another advanced ultrasonic technique: time-of-flight diffraction.

Plant Integrity

Teletest Focus on high temperature pipelines

Paul Jackson Manager, Plant Integrity Plant Integrity is a subsidiary of TWI that specialises in the provision of guided wave ultrasonic technology to detect flaws in structures – primarily pipelines and other tubulars.

In 2016 the company maintained its success of previous years, exploiting its Teletest® guided wave technology through further development of its products and the delivery of inspection services, training and bespoke solutions to a variety of industries all over the world.

Main successes were as follows:

Very strong Teletest system sales Launch and sales of high temperature Teletest tooling for pipeline inspection at service temperatures of 240°C Delivery of large order book of collaborative projects funded by the EU and UK government Projects in strategically important areas of tank monitoring, inspecting buried pipelines and permanent monitoring of pipes Bespoke automated data processing software for key nuclear client

Teletest Focus™ guided wave testing is a proven technique for testing in-service pipes for degradation such as corrosion. To satisfy industry demand Plant Integrity has developed a high temperature Teletest Focus variant giving operators more flexibility and capability.

The original Teletest Focus equipment was limited to a maximum of 120°C, which was considered acceptable for most process pipes and transmission lines. Due to an increasing industry need, there was a requirement to inspect at higher temperatures while the pipeline was still in service, allowing remedial action to be taken quicker, minimising costly delays.

Plant Integrity’s design and development team reviewed the current transducers, modules and collar and found a solution that kept the original design. The transducers were significantly redesigned but without changing size or shape, all module materials were replaced with high temperature plastics, and heat resistant insulation was added to the existing collar design.

Extensive testing included cyclic temperature testing and cooling, the design team combined the right materials, and insulation to boost temperature capability of the equipment up to 240°C. Post-test analysis showed no evidence of heat damage to the equipment or deterioration of signal to noise ratio which confirmed the design approach taken by the team.

This high temperature system was field tested by a Teletest Focus operator in North America who successfully tested the system at 350°C by keeping the tool on pipe for a minimum amount of time, then allowing the tool to cool thoroughly, confirming the design approach taken and robustness of the construction.
