Abstract

A process variant for laser beam welding of aluminum alloys using high-power CO₂- and Nd:YAG-lasers is presented. In this variant, the advantages of the cw- and the pulsed laser welding are combined by modulation of the laser beam. For quite a lot of Al-alloys fairly good welding results are achieved on the butt and overlap joint. The weldability ranges become larger and it is possible to weld with lower mean powers than in the cw-operation.
