Trending
It’s Heading This Way A ringside view of trends in laser manufacturing for battery, electric drives and mobile power electronics
A
utomotive manufacturing is a key future field for TRUMPF. The rate of innovation in this field is high. Alongside the variety of materials used in the vehicle body and power train, the increasing trend toward electric vehicles represents a key field with many new applications. Find out about trends in laser manufacturing for battery, electric drives and mobile power electronics. Rapid change opens-up opportunities It is the right time to develop methods of mass production EVs. The good news is that this accelerated upheaval in drive technology offers real opportunities to newcomers. In the past 30 years, automakers have clearly shown that laser is a material processing tool they can use to execute flexible, high-precision steps on the factory floor in very little time. Many of the key car components such as body, interior, lightweight components, brakes, etc. aren’t going anywhere. Even in 2025, electric cars will still need doors and the carmakers already know how to make them efficiently. But now three new fronts are opening up : batteries, electric drives and high-power electronic systems. EV sales are currently running at about 2million a year, and forecasts suggest that will rise to 40 million in just a few years’ time. To keep up, many industry players will once again have to rely on laser material processing. Battery times three What we loosely refer to as a battery is, in fact, a complex entity. There are three components that hold the key to the efficient manufacturing of energy storage devices for electromobility: battery cells, battery modules and battery packs. Lithiumion battery cells are built up in layers: copper foil and coated aluminium layered together with the electrode foils of lithium metal oxide (cathode) and graphite (anode). Each of the different foils is approximately 100 microns thick, and the easiest way to cut them is with a
short-pulse laser. After adding the liquid electrolyte, the next step is to seal the cell with a cap and fit a pressurerelief valve. It is essential that the welds completely seal the cell, but it is equally important that they do not penetrate too deep since this would render the cell useless. So, once again, battery-cell manufacturers turn to the delicate and reliable touch of the laser. Today’s market for battery cells is largely divided amongst volume manufacturers in China, South Korea and Japan. In contrast, the market for battery modules is still open – so far, no standards have been set for the rest of the process. Making electric motors faster As the industry seeks ways to accommodate volume production, companies are also starting to reconsider some of the traditional, yet sluggish, manufacturing methods currently used for electric motors. One example is the coil. Normally, the stators in electric motors are provided with a winding of copper wire. Each individual slot in the stator is wrapped in a winding that goes in and out, almost like knitting. That takes time – and is tough to automate. The auto industry considers this process to have reached the limits of its productivity and is banking on a new technique known as hairpins. This involves using a compressed-air pistol to fire a rectangular copper wire similar to a hairpin straight into each slot. This method is several times faster – just one shot per slot – and it completely fills the space with copper, which increases the motor’s efficiency. The protruding parts of the hairpin on both sides are then pressed onto each other using a mask or are jammed or twisted together. The problem is that the hairpins are sometimes slightly out of alignment with each other after this process, with unsightly gaps in certain places. That’s when scanner welding comes back into play: a camera in the laser optics determines the
orientation of the objects within the space and finds the ideal welding point within just a few fractions of a second. The beam focus oscillates and, in little more than a minute, all 200 of the welds required for each motor are finished – and the laser is ready to weld the connections for the next motor. The second benefit of using high-precision scanner laser welding for hairpins is that it reduces the overhang of the weld seam to almost zero. The slots and hairpins can move closer together, and that means the motor takes up less space. At this point the copper hairpins go under the laser for the second time, having already had their insulating enamel removed by a pulsed nanosecond laser earlier in the process, either directly on the coil or before winding. Mechanical methods to remove the enamel – such as planing and milling – can no longer keep pace with the required level of productivity. Mobile power electronics For the first time, power electronics such as chargers, transformers, rectifiers and batterymanagement systems are making massive inroads in the realm of cars and their charging infrastructure. While the electronics in cars powered by fossil fuels had to make-do with a 48-volt battery, electric cars will soon be using voltages as high as 800 volts. Once again, the companies that manufacture these kinds of power electronics are faced with the dilemma of how to mass-produce these components – and how to make them as small as possible. That’s because every millimetre counts for carmakers when it comes to battery-pack size and installation space, and engineers may decide that even the millimetre-sized contact pins are too big. What’s more, weld spatter can become a serious problem for contact connectors: a large spatter droplet could easily consign the virtually finished component to the scrap heap. Even worse, spatter could end up stuck to the component, initially harmless, but then suddenly come loose later when the car is in motion – causing a short circuit and bringing the car to a standstill. The problem is that space is tight when it comes to welding electronic components, so there is simply no space for devices designed to intercept spatter. That’s why engineers opt for a disk laser. Combined with special technology that simultaneously overlays two welding foci, a disk laser can create virtually spatterfree welds even in small, cramped environments. The laser welds directly in the groove, which keeps the contact pins below three millimetres. More valuable millimetres shaved off the size of the components – and every little bit helps!

The approved beam guiding systems ensure a safe operation under industrial conditions. With NOVA it is possible to look beyond the obvious laser welding. Nova is designed to perform tasks like Drilling, Annealing and Hardening. Laser Hardening is one of the widely used industrial applications. Laser hardening is a method aimed at improving component wear behaviour. One advantage of using a laser is that the amount of heat input is comparatively low, so heat is transmitted into the base material relatively quickly. Self-quenching is produced as a martensitic structure is formed and the hardening layer is 'cooled.' Laser micro-drilling can be used to produce micro-holes in any material. SLTL Group’s NOVA use its own proprietary laser micro-drilling systems, sub-contract micro drilling and process development services for micro hole production and R&D. High welding joints quality It offers large weld penetration, minor deformation, pollution-free welding sites, easy and beautiful appearance, no need or just simple post-treatment. It gives the strongest welds and high-quality joints. This innovative system ensures superior quality while delivering 40-100% more output compared to existing conventional welding Systems. Boosts profitability Latest advancement of beam sources and sensor systems reduce operating costs and increase the speed. This machine is known for increasing the efficiency of large scale industrial workflow. Core objective behind making this SLTL Laser system were to lower costs per part (CPP) and costs per cut, reduce lead times and downtime, as well as increase overall productivity, which will inevitably lead to increased profitability.
Compact, mobile and yet strong NOVA is an equipment that combines the toughest quality requirements with extreme cost ef ficiency. SLTL Laser Welding Machine is constructed very compact and gives the strongest Weld joints.
