Nanosecond pulsed fiber laser as a tool for laser micro welding

Procedia CIRP, 2020
Abstract Laser micro welding is – due to its local and limited thermal input into the parts – a well suited joining technique for the contacting of battery cells, modules and packs for electrical vehicles. The most common laser micro welding processes employ a fiber laser emitting in the infra-red range in continuous wave mode.

Guidelines in the Choice of Parameters for Hybrid Laser Arc Welding with Fiber Lasers

Physics Procedia, 2013
AbstractLaser arc hybrid welding has been a promising technology for three decades and laser welding in combination with gas metal arc welding (GMAW) has shown that it is an extremely promising technique. On the other hand the process is often considered complicated and difficult to set up correctly. An important factor in setting up the hybrid welding
