PRODUCTION OF WELDED CAN BODY

摘要

PURPOSE:To form a weld zone having the width equal over the entire length without generating deviation in the overlapped parts by working preliminarily the contact surfaces of the overlapped part in such a way that said faces incline with respect to the electrode surfaces of wire electrodes and that the ends mesh each other. CONSTITUTION:The overlapped part 9 of a can body forming body 8 formed of a metallic blank is so formed that the surfaces 4a and 5a mesh each other in the transverse direction and that the contact surfaces thereof incline in the circumferential direction of the body 8 with respect to the electrode surfaces 12a and 13a. The welded can body having the weld zone satisfactory over the entire length is thus produced without generation of the deviation toward the outside of the circumferential direction in the superposed part 9, more particularly the part near the front end and rear end thereof even if relatively high welding force is exerted thereto in the stage of welding.
