Abstract: According to the invention, a welding of the visible parts of the bodywork of a motor vehicle (SC) is accomplished through a capacitor discharge welding. A welding gun (5) is moved together with a pulse transformer by the arm of a robot (1). By using a welding coil of reduced size and welding boss having proper shapes and sizes, the operating efficiency of the transformer and the gun (5) is improved whereby both devices can be made light-weight and compact and can be secured to the wrist of the robot arm (1). By using a capacitor discharge welding, and suitably shaped electrode heads, the welded areas are scarcely visible or completely unnoticeable to the final user of the vehicle.
