PURPOSE:To secure a normal resistance welding and carry out the normal welding, even if a weld chip is not welded, by the other weld chip and providing two pair of weld chips along the proceeding direction of the welded materials. CONSTITUTION:A weld chip 8 may be floated in case of a pair of a weld chip 8, stage generating between a weld tool 36 and a back edge of a work 2 and clearance between the two and the weld faults may occur. However, by providing two pair of weld chips 8, 8a to the direction of a work 2 with the specified interval opened, the back weld chip 8a contacts with a weld tool 36 even if it floats temporarily by the stage part when a weld chip 8 transfers from the back of a work 2 to a weld tool 36, and any weld faults may not occur. |
