Abstract
A device for connecting two workpiece parts by means of laser beam welding. Producing a simply constructed and cost-effectively manufactured device for flat welding workpiece parts, with simultaneous compensation of workpiece tolerances, is achieved by a weld seam pattern with a number of weld seams arranged downstream of an adapted pressure unit of a laser beam source. The pressure unit has a plurality of channels extending through it with channel walls. The channel walls are a lattice-like arrangement of the first and second pressure elements which have integrated means for compensating tolerances, and which are designed to press the workpiece parts against one another in the z direction.
