Abstract

PURPOSE: To flatten the step of the forge-welded part and prevent formation of oxide film, by forge-welding the overlap part of can drum molding under pressure between the rotating electrode and lengthwise electrode.
CONSTITUTION: A can drum molding 1 is sent forth into the position of a lengthwise electrode 6 by means of a feed rod 4. At the same time, holding wings 9 move from the right and left side and a supporting tool 10 advances to secure the can drum molding 1 on a mandrel 3. In this case, it is improtant that the entire width of an overlap part 2 be in contact with the surface of electrodes 7 and 12. Then, a sliding plate 16 is moved to the right to clear the engagement between a bearing bottom plate upper surface 13a and protruding part 23a. The electrode surface 12 of rotating electrode rotates on the electrode surface 7 of lengthwise electrode, thereby turning the overlap part 2 to the right while pressing with a pressure spring 17. The current in this process passes through the rotating electrode, overlap part and lengthwise electrode to perform welding.
