PROCESS AND DEVICE FOR WELDING SEAT STRUCTURES, AND SEAT

摘要

The invention relates to a process and a welding device (1) for welding seat structures (15) of seats (21), wherein a plate-shaped cover plate (17) of the seat structure (15) is welded to at least one U-shaped supporting profile (20) by means of a laser beam (3) directed at the rear side of the cover plate (17). Beforehand, the webs (16) of the supporting profile (20) are measured using a measuring device (9) carried along by a manipulator (6), wherein the path taken by the manipulator (6) and the intended weld seam (13) are aligned on the basis of the measurement result. The cover plate (17) is subsequently put in position and then welded to the webs (16) by means of a beam head (5) carried along by the manipulator (6).
