Nanosecond pulsed fiber laser as a tool for laser micro welding
Autor: Arnold Gillner, E. Haddad, Alexander Olowinsky, Johanna Helm
Publikováno v: Procedia CIRP. 94:571-576
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 emp

Combined laser beam soldering and welding process for electrical contacting
Autor: Ansgar Meise, Johanna Helm, Alexander Olowinsky
Publikováno v: Laser-based Micro- and Nanoprocessing XV.
Due to the increasing power, contacting of high-power semiconductor components requires ever larger cross sections, which can no longer be handled by conventional joining processes such as ultrasonic wire and ribbon bonding. To generate larger cross
