In the production of welded joints of body panels of motor vehicles and the like sheet metal parts by means of laser beams, the problem arises that the body panels are not dimensionally stable part and to spring back after shaping of the sheet into the desired shape for the part, thereby to between to be joined sheet parts part gaps are created. In a device for laser welding with a robot with Andruckzangen an advantage of laser welding, namely the high speed can not be exploited because of the adherence and release of the pliers. body parts, laser welding of vehicle and the like sheet metal parts is possible with low temporal and machine costs, that at least the non-dimensionally stable sheet-metal part (38) through a master bed (38a) fixed in its intended shape with the other to be welded sheet metal part (38b) in brought mutual desired position, the sheet metal parts (38,38b) are stapled at discrete points to form a dimensionally stable body part and then the sheet metal parts (38,38b) with a Lasernahtschweißung firmly and tightly joined together, the side facing the laser head (12) plate (38b) by melted and the abge faces the laser head plate (38) is at least partially melted.
