Abstract
The invention relates to a device for clamping and welding pieces of sheet metal (13, 14) which are placed against one another, preferably for use in the area of automobile manufacturing. According to the invention, a bracket (3) is fastened to a mounting flange (1), preferably of a robot arm. Said bracket (3) comprises a clamping tool (6) and a welding head (10). The energy beam (16) of the welding head (10) is directed into the welding gap between the pieces of sheet metal (13, 14). Using the mounting flange (1), the bracket (3) and/or the welding head (10) can be displaced in a linear guide (4), said guide being situated opposite the hydraulic cylinder (7), according to the progression of the weld seam (11). In addition, stop elements (8, 8′) for detecting the position of the edges of at least one of the pieces of sheet metal (13, 14) are arranged on the clamping tool (6) in order to position the pieces of sheet metal (13, 14) with regard to one another and/or to the welding head (10).
