Nanosecond pulsed fiber laser as a tool for laser micro welding
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 infrared range in continuous wave mode. Recently however, it was shown that a nanosecond pulsed fiber laser, usually used for ablation applications, can be used for joining as well. The aim of this paper is to examine welding dissimilar materials with a nanosecond pulsed fiber laser.
