TRUMPF will present an innovative and integrated laser welding and stripping system for hairpin welding and stripping process that are being used in mass production. For stripping process, high power nano-second laser is used to selectively remove the isolation layer of the hairpin withtout damaging the copper surface. For welding, high power lasers with BrightLine technologies are used to produce spatter free and pore suppressing welding results. Vision system and OCT sensor are integrated in the system to ensure process robustness and quality assurance for large scale eDrive production.
