Working direction

Functions of Coating / The Usage and Application of the Electrode Due to the physical properties of the coating material, core wire has a higher melting rate than the coating material. Therefore, 3 to 5 mm crater formation occurs at the tip of the electrode. Particularly in cutting and piercing applications, this crater formation enables the operation of the electrode penetrating into the melting piece without short circuit. Pieces up to a thickness of 10 mm can be easily cut with this electrode. For thicker pieces (10 mm), electrode should be moved up and down in the direction of material being cut to move away the melted material. In piercing applications, electrode should be perpendicular to the work piece.

It is used for beveling, weld preparation of cracks and for gouging of armour steels, air hardenable steels, stainless steels, cast irons, hard metals, work hardenable and difficult to machine materials. The surface is clean and seldom requires further dressing. Metal removal speed depends on the electrode diameter, ampere selected and to the thickness of the piece.

MAINTENANCE and REPAIR WELDING CONSUMABLES

"KOBATEK" helps you to cut spares and repair costs Because wear exists wherever there is motion, nearly every industry encounters wear problems. Excessive wear causes billions of dollars to be lost annually through: unplanned downtime, repetitive replacement of costly parts, inordinate maintenance costs, lowered production efficiency and losses of sales due to poor product reliability. Kobatek repair and maintenance welding electrodes have been instrumental in reducing losses and increasing cost savings for companies in a number of diverse industries and applications. Companies use Kobatek products to : Reduce cost : Fewer man-hours for repair and maintenance jobs; minimized downtime and rejects; reduction in purchases of spare parts, energy and resources. Prolong equipment time : Surfacing extends life 30-300 %, depending upon application, as compared to that of a non-surfaced part. Reduce down-time : Save dismantling time and downtime due to replacement delays; minimizes re-fitting time, etc... Reduce inventory of spare parts : There is no need to keep numerous spare parts when worn parts can be rebuilt. There are basically two main areas where Kobatek electrodes are used : 1. The rebuilding of worn metal parts to their original dimensions. This is accomplished with buildup or with build-up and overlay welding. 2. The protection of new metal parts against the loss of metal. Hardsurfacing overlay is used on both new and/or original parts where the parts are most susceptible to wear. The higher alloy overlay offers much better resistance than that of the original base material. This usually increases the work life of the component up to two or more times that of a part which is not surfaced. With over 20 years experience in the field of repair and maintenance welding, Kobatek can recommend and supply the most cost-effective solution to any repair-maintenance and welding problems. Kobatek offers you a complete range of welding electrodes for every repair and preventative maintenance need. Kobatek research teams are constantly seeking better methods of combating wear and welding problems; creating new products for new preventative maintenance and welding problems, and improving existing products for old problems. New products to match operating requirements in your plants can also be developed. This part briefly outlines the Kobatek product line which includes electrodes for: surface preparation, cast irons, steels, stainless steels, hardfacing, copper and aluminium alloys.

Wear Factors Wear is a general term used to describe a progressive deterioration of a surface with loss of shape, often accompanied by loss of weight due to the creation of debris. We have to understand the wear factors involved before making a hard surfacing product selection. There are seven major types of wear which are caused by mechanical and chemical actions: Mechanical causes of wear : Abrasion, impact, erosion, cavitation, friction Chemical causes of wear : Corrosion and heat. Abrasion : Abrasion is the most common form of wear. It is caused by foreign materials (non-metallic materials such as sand, oxides or grit) moving over a metal part. The worn surface can be recognized by its polished appearance or by very fine scratches in the direction of particle movement. It can be broken down into three main categories : 1. Low-stress scratching abrasion : typical components subjected to this kind of abrasion include: agricultural implements, classifiers, screens, slurry pump nozzles, sand slingers and chutes, etc. 2. High-stress grinding abrasion : typical components subjected to this kind of abrasion include: augers, scraper blades, pulverizers, ball and rod mills, muller tires, brake drums, roll crushers, rollers sprockets and mixing paddles etc. 3. Gouging abrasion : typical components subjected to gouging abrasion include: dragline buckets, power shovel buckets, clam shell buckets, gyratory rock crushers, roll crushers and jaw crushers, etc.

Abrasion

Impact : Wear by impact is the result of a succession of local shock loads on the material surface. When the stress exceeds the elastic limits of the metal, the metal deforms both beneath the point and laterally across the surface away from the impact point. Some of the effects of impact are: fatigue, cracking, flaking, compression and deformation. Typical components subjected to impact include: coupling boxes, crusher rolls, impact hammers, impactor bars, railroad frogs and crossings.

Impact

Erosion : It occurs in liquid or gaseous media, when extraneous, fine and hard particles strike a surface at an angle of incidence. Erosion can be considered a combined form of impact and abrasion. Grit-blasting is a technological application of this phenomenon. Erosion wear involves two typical mechanisms: 1. In cases of vertical impact we are dealing with local phenomena, which can lead to both elastic and plastic deformation, with grooves on the worn surface. 2. In cases of oblique or glancing impact by solid particles, the mechanism of surface damage involves the formation of chips.

fine particles

conventional metal

Erosion

Cavitation : This wear results from the rapid formation and collapse of tiny gas bubbles in a liquid. This causes high speed localized pressure changes or explosions creating shock waves that impact on the base metal surface resulting in local deformation. The damage to the surface arises from a similar mechanism to that of erosion by impact deformation, except that in the case of cavitation the solid abrasive particles are replaced by microwaves that produce pitting fatigue, subsequent micro crevices (fissures) and the removal of metal.

127

Cavitation Corrosion : It is deterioration of a metal by a chemical or electrochemical reaction between the metal and the environment such as scaling and pitting caused by oxidation when a metal is heated, or by acids eroding the base metal. The most common type of corrosion is rust. Rust transforms the surface of a metal into oxide which eventually flakes off, thus reducing the original thickness of the metal. In most cases, several different types of wear work together, with a combined destructive effect which is often greater than the sum of their individual effects. To propose an effective solution to complex combined wear problems, one approach is to analyze the exact manner in which the mechanisms are interacting. This brief description of the main types of wear shows that a detailed theoretical evaluation of any given wear problem is highly complex. But you can easily find a solution with the appropriate special KOBATEK alloys.

acidified water (electrolyte)

Corrosion

rust carbone impurity (anode) plain steel (cathode)

High Temperature : Heat affects the metal's microstructure and generally reduces its durability. A major cause of metal failure from high temperature service is the thermal fatigue (fire cracking) that results from repetitive intense heating followed by cooling. The repeated expansion and contraction caused by this thermal cycling eventually exceeds the ability of the metal to recover and causes deep cracking. The most common form of wear caused by heat is probably oxidation. This takes place during the build-up of an oxide layer. Wear occurs when the layer is broken away by a cycle of expansion and contraction, and the whole oxidation operation is repeated. Typical components subjected to high temperature wear include: continuous caster rolls, steel mill work rolls, hot forging dies, tongs and sinter crushing equipment.

Adhesion and Friction (metal-to-metal) : This wear results from the sliding or rolling contact of one metal surface against another. To the naked eye, metal surfaces may appear smooth and even highly polished, but under a microscope they show definite hills and valleys. As metal surfaces slide against each other, the high areas (hills) are broken and tiny fragments of metal are torn away. Typical components subjected to friction include: steel mill rolls, undercarriage components, shear blades, shafts, trunnions and non-lubricated bearing surfaces.

Welding Methods In addition to the properties of its chemical elements, the properties of the weld filler metal is based on the following factors : - electrode diameter, - arc length, - preheating temperature, - current and type of polarity. The last factor leads to two welding methods : METHOD - A High Current Operation It is suitable for large and thick sectioned components. It enables high speed welding. This method is particulary used for assembly and machine parts where pieces are removed from the surface and for multipass filler welding applications. METHOD - B Low Current Operation It is used to eliminate the overheating of small and thin sectioned components. It also provides a protective layer in the weld metal due to the limited melting of the base metal. Minimum fluidity and liquidification is obtained on the base metal.

Kobatek 111 KobatekÂ 111 is used for ferrous or non-ferrous metals where grooving is necessary without supplementary gases and special electrode holder. For preparing sections prior to welding, gouging out old or defective weld metal, removing flash and risers. All these operations can be carried out in all positions; except vertical upwards. A thick, specially developed exothermic coating produces a forceful gas jet which blows the molten metal away, to give a smooth, clean groove. A finishing operation is unnecessary. RECOMMENDED PROCEDURE : Strike the arc with the electrode normal to the workpiece and then immediately incline the electrode at an angle of 15-20Â° to the workpiece. Point the arc in the direction of travel, move the electrode forward to melt the metal and then pull it back to allow the gas jet to blow the molten metal away.

Handling and Storage of the Covered Electrodes Manufacturing : Covered electrodes are manufactured by extruding different materials on a core wire. As binder for the coating materials silicates are used which contain 60 % water. The electrodes are dried at different temperatures depending on kind of the electrode. Acid, rutile and cellulosic type of electrodes are dried up to a moisture content of 0.3-2.0 %. Basic and alloyed types of electrodes are dried; actually baked at higher temperatures up to 500째C and the final moisture content is very low. Humidity of the Coating : Covered electrodes must be handled carefully. Electrodes and their coverings can be damaged through absorption of moisture. Too high a moisture content in the electrode covering can be dangerous and therefore must be avoided. All the electrodes have a certain moisture content, which varies according to the type. Moisture content of the covering of Askaynak electrodes is controlled strictly before they leave the factory. A limited moisture content is normal and has no effect on weld quality. The moisture limits actually have a large safety margin in moisture content when they leave the factory. All electrode coverings are hygroscopic and absorb moisture from the air depending on the relative humidity of the air. At higher relative humidity levels ; e.g. 90 % the covering of basic electrodes absorbs moisture so quickly that after exposure for one day the electrode cannot be used anymore. Acid, rutile and cellulosic type of electrodes are not as sensitive as basic electrodes but they will all pick up moisture if left unprotected. It is not only direct moisture in the air, which can damage the electrodes but also condensation. Specially on high relative humidity levels and at large temperature differences between day and night condensation can occur. The dew wets the packages and this moisture is gradually absorbed by the electrode covering. Humidity in the coverings of the electrodes can cause severe damage to the weld. It can cause porosity in the welds. Unfortunately porosity is not always visible to the naked eye but radiography reveals at once. As a source of hydrogen it is the main cause for hydrogen cracking in the welds, which is very dangerous. There is the danger of underbead cracking in the heat affected zone of the parent material. Packing : Because of the danger of moisture pick-up the packages of the electrodes should be suitable to avoid this danger. Unless stored in appropriate conditions coated electrodes will remain unaffected and provide satisfactory welds. All of Askaynak covered electrode boxes are tightly wrapped in polyethylen. For sensitive welds tin-can boxes are available. Plastic boxes are used for stainless steel type of electrodes.

Handling and Storage of the Covered Electrodes Storage Conditions (*) : The electrodes must be kept in their original packages. The electrodes should be protected against rain, damp and dew. The relative humidity level at the storage place should be 40 % and less. The temperature of the storage should be constant and above 15°C. The boxes should be kept on shelves or pallets avoiding to contact directly the floor and the walls. When welding outside loose packets of electrodes should not lie about unprotected on the site. Electrodes should not be taken out of the store in quantities greater than necessary for daily or two days consumption. Redrying : Rutile Types : Redrying is not necessary. In case of high moisture redrying at 100-150°C for 1-2 hours is recommended. At lower drying temperatures electrodes should be kept longer. Cellulosic Types : Cellulosic type of electrodes are not very sensitive to moisture pick-up. Redrying must be made very carefully otherwise the coating can get cracks. In general redrying is not recommended for cellulosic electrodes. In case of a necessity the drying temperature should not exceed 70°C. Basic and Alloyed Electrodes : If the electrodes are stored in recommended storage conditions (15°C / 40 % relative humidity) and in original packages there is generally no need for redrying. When the plastic wrappings of basic type of electrodes are opened the electrodes ought to be put into a heating cabinet at about 50°C. If the boxes are opened and exposed to open air for more than 2 hours redrying is recommended. Basic and alloyed electrodes are dried for 2-3 hours at 250-400°C. It is not recommended to redry the same electrodes more than 3 times.

(*) These storing conditions are necessary for basic type of coverings. In case of rutile and cellulosic type of electrodes the conditions are not as tough as for basic type of coatings.
