Abstract

PURPOSE: To expose the base sheets of chromated steel sheets by simple means adaptable for high speed production lines without producing any fine particles by beforehand subjecting the overlap part of the steel sheets to be welded to indenting.
CONSTITUTION: End parts 11, 12 to form the overlap part of a can barrel blank 10 for food canning are subjedted to linear indenting in parallel with the end edge by freely revolving rolls 1, whereby worked parts 15, 15' are formed. Thence, the blank 10 is rounded to a cylindrical shape, the parts 11, 12 are overlapped, the overlapped part 13 is inserted between upper and lower electrode wires, and while said part is grasped by pressure with the electrode wires, electricity is conducted to the wires, and welding is accomplished. Then, the occurrence of expulsion and surface flash is extremely slight, hence sufficient coating can be made by protecting paint and the side face joint having sufficient weld strength is obtained.
