The subject of this thesis is the further development of the local laser softening of high
strength steels. In order to achieve more homogeneous softening over the board thickness at
high feed rates  two approaches for process adaptation are investigated. For a simultaneous
process of laser cutting and laser softening  a processing head  is developed. The implications
of laser-softened parts in the joining zones for resistance spot welding on crash performance
are demonstrated.
