Abstract
The present invention relates to a process for joining workpieces made of zinc-containing aluminum alloys by laser beam welding, in which process a layer consisting of vanadium is introduced into the joining gap between the workpieces to be connected to avoid the formation of pores, and the workpieces are then connected to one another by laser beam welding.
