Whilst Asia remains the stronghold (projected to reach 800GWh by 2025), Europe is expanding rapidly with a projected production capacity of 450GWh/year by 2030. Laser welding has emerged as the optimal welding technique to respond to the increasing demand for EV battery manufacturing; being 4-5 times faster than the current welding processes.
The laser welding process allows processing of parts in the micron range but reduces the surface quality of the processed parts at the same time. Furthermore, weld defects can occur due to process instabilities caused by the low absorptivity (<5%) of copper for infrared radiation.
For the majority of applications, laser welding has shown an advantage compared to other ones such as Resistance Spot Welding, Ultrasonic Welding, or mechanical fastening .
Of course, if someone looks beyond the battery welding applications many in-process quality assurance approaches are available for welding . In the case of laser welding, the in- process monitoring is mainly based on imaging, acoustic emission, and E/M signal techniques in general .
The effect of ultrasonic excitation (vibration) during the laser welding between dissimilar metals (i.e. aluminium, nickel, copper) will control the thickness of the intermetallic compound layers during solidification and reduce or avoid the generation of defects which can severely limit the mechanical properties of welded joints.
