method for welding two-piece laser brazing, equipment for applying said method and applying said method and equipment in particular for sheet metal bodywork of an automotive vehicle

摘要

The invention relates to a method for the braze-welding of two steel parts (1, 2), in which: a laser beam (3) and a metal filler wire (4) are moved continuously along the connecting line between the two parts (1, 2) in such a way that this laser beam (3) continuously melts the metal filler wire (4) so as to form a continuous weld seam (5) between the two parts (1, 2); and a shielding gas is blown onto the weld seam, characterized in that this shielding gas is compressed air free of gases other than those contained in the ambient air.
