AbstractLaser welding is a viable alternative to conventional joining methods for e‐mobility processes such as rotor welding or battery production due to its non‐contact and precise processing technology. However, highly reflective materials such as copper and aluminum are used in these processes. Their low surface absorption and high thermal conductivity require a special design of the laser system to prevent scattered radiation and the material temperature from rising above 80 °C, because welding generates quite a bit of heat.
