This design enables the automatic welding of metallic drum covers. It is integrated into the IAF workshop of the nuclear processing and conditioning plant. Automatic welding station in a restricted area. Sealing of nuclear waste drums using the MIG welding process for obtaining either a continuous weld seam on the cover circumference, or a discontinuous weld composed of equidistant weld seams. The pieces to be welded are made of steel and may be slightly oxidized. Given the welding process, a 1 to 2 mm (. 04” to . 08”) play between the two pieces to weld may be accepted in order to obtain a tight connection. The supervision of the illuminated arc welding operation is performed by a video camera. A carriage drives the drum under the machine. The approach, the clamping and the welding are all automatic.
