Abstract

PURPOSE:To simultaneously weld plural points of plural sheets of laminated metallic sheet, and to make stable and good the result, by arranging laminated metallic sheets to be welded between the leg groups, by drilling the through holes in both side faces of these sheets, and by pressing and supplying electricity. CONSTITUTION:In the spot welder 23, the stationary leg group 2 on one side is formed by gathering legs 21, 22, which are supported by the supporter frame 20 so as to be insulated; and the movable leg group 3 on another side is formed by gathering legs 31, 32, which are movably supported by the supporter frame 30 so as to be insulated. The laminated metallic sheet 1 is formed by laminating sheets 11, 12, 13; and the through holes 110, 130, are drilled in the sheet 11 on one side, and in the sheet 13 on another side. The legs 21, 31, and 22, 32, of both leg groups 2, 3, are respectively facing each other interposing the sheet 12; the legs are selectively coupled like as (21, 31), (21, 32) or (32, 31), and are used for the electrodes for supplying the welding power as the conductive material, for welding sheets 12, 13, or 12, 11. As a result, both of weld points 1213, 1112, are welded and fixed to the middle sheet 12.
