Device for welding sheet metal joints uses a laser beam from a laser welding head and a position holder to determine welding direction.

摘要

A laser welding head (LWH) (3) moves along with controlled motion on a two metal sheet flange edges (6,7) that overlap in an overlapping area (8). The LWH links firmly to a position holder (4) pressing on a direct welding point (5). The surfaces of the metal sheet flange edges have a layer to form protective layer steam during welding.
