PRODUCTION OF WELDED DRUM CAN

Japanese Patent JP2775382

B2

PURPOSE: To fill a ring-like clearance of the joining part inside a can and to easily wash in a reusing time by welding around the joining part of the drum body after fastening them with winding and a top plate or a bottom plate from the outside.
CONSTITUTION: Arc welding is executed with TIG or plasma, etc., at the outside of a can and from the side of a bottom plate 2 of the back side of the drum body 3 while rotating with laterally mounting the drum can fastened with winding after the projection like bottom plate 2 is fit into the drum body 3. A torch 9 is installed in an angle against the bottom plate 2, the drum body 3 and the rotating direction, the arc 10 is generated aiming at a meeting beginning part 14 of the bottom plate 2 and the drum body 3 or at the neighborhood of the bent part of the bottom plate 2. Therefore, because the molten metal is turned around the hanging surface of the bottom plate 2 and filled in the ring like clearance as the groove, the build up welding 15 can be formed without using an additive. The same method as the bottom plate can be also adopted in joining the joining part of the top plate.
