Abstract
We demonstrate the use of Variable Beam Profile (VBP) lasers for welding e-mobility materials. The VBP laser uses dual beam output to produce a central spot, surrounded by another concentric ring of laser light. The use of VBP lasers results in a welding process that is more stable and consistent during welding. This paper highlights welding results achieved using a VBP fibre laser, with power ranging from 6kW to 12kW on weld joints including dissimilar joints between copper and aluminium-based alloys. Results from VBP lasers are compared with those obtained via e.g. pulse shaping of traditional single beam lasers.
