The CO - and solide-state laser are adopted mainly in the automotive engineering. There are many examples of applications including the laser technology advantages. These adoptions take place by means of typical used components, such as for laser cutting of hydroformed tubes and hotstamping parts and also for laser welding of power train parts. The VW Group is the leader of laser applications in the global competition. Joining tasks are overlap welding, brazing of edge joints and the VW typical fillet joint on the trunk-lid and roof. The materials processed are hot dipped and galvanized zinc-coated automotive steels. The VW Golf, VW Touran and VW Jetta hold the world record for laser applications. Arguments to apply laser technology: Increased process speed (joining); increased strength of the modules compared to most alternative joining methods by continuous welds; narrow or no flange can get welded, which allows weight reduction; high flexibility of the laser technology, the same laser can weld, braze and cut; additionally, the laser beam can get directed to different work cells by means of fiber optic cables.
