The use of Nd:YAG laser weld for large scale volume assembly of automotive body in white

This paper describes how Nd:YAG laser welding and laser brazing technologies became useful and applicable in huge scale production lines at the beginning of the millennium. The shown case concerns the laser welding and laser brazing processes of steel roof and side panels with material addition and also laser welding of complete body geometry without material addition, both using two stations for two different models.
