摘要： PURPOSE:To continuously seam-weld a three-ply part and a two-ply part of metallic sheets by bending the ends of the metallic sheets to abut these on each other and subjecting the three-ply part wherein a tabular suspender is sandwiched to seam welding by using electrode rolls having thick walls and the peripheral contact surfaces with a rounded shape. CONSTITUTION:Stainless steel face materials 13 and 14, and the suspender 11 are pressed between the electrode rolls 8 and electrified. The electrode rolls 8 have 15-30 times thickness as much as stainless steel face material thickness and are made of a discoid Cu alloy with good heat conduction and the peripheral surfaces thereof have the 50-100 times radiuses R as much as stainless steel face material thickness and are rounded and provided with water-cooled jackets 8a. When the wall thickness of the electrode rolls 8 is small, high current is not allowed to flow through the electrode rolls and when the wall thickness is large, heat loss thereof increases. When the radiuses R of the peripheral surfaces are small, dents are too deepened and when the radiuses are large, bearings run short. The high current required for the three-ply part is charged and the three-ply part and the two-ply part are seam-welded continuously.
