Abstract
PURPOSE: To prevent the increase in oxide films by blowing inert gas of a high speed and low speed in two stages over the specified section during passing at the weld point and right after this, in the formation of the side seam portion of a can barrel by electrode rlllers.
CONSTITUTION: At the time of forming the side seal portion of a can barrel, the air layer forming thick oxide films is expelled by the inert gas of a high speed and low speed. More specifically, the overlap portion β1 of the barrel plate β is passed at the weld points W, P between electrode rollers (a) and (b) and is thereby welded. The inert gas of the specified pressure is supplied from feed ports 4e, 8e and 4f, 8f, and since the high-pressure chambers 4b, 8b have one jet orifice, they maintain a high pressure and since the low-pressure chambers 4c, 8c have many jet orifices, they maintain a low pressure. First, the high pressure gas G1 is blown at a high speed from the jet orifices 4g, 8g to the weld points W, P diagonally against the travel direction at a high speed to expell air, during which time welding is done. Next, the low-pressure gas G2 is blown diagonally to the side seam portion α1 at a low speed from the jet orifices 4h, 8h to perform rapid cooling while expelling air.
