| 摘要 |
The present invention relates to a seam welding method and a seam welding device (10). The seam welding device (10) sandwiches between a first roller electrode (26) and a second roller electrode (28) a laminate (100), which is formed by laminating a plurality of workpieces (W1, W2, W3) and disposing the thinnest workpiece (W3), which has the smallest thickness among the workpieces (W1, W2, W3), on the outside, to carry out seam welding. The second roller electrode (28) which is in contact with the thinnest workpiece (W3) is disposed further along the direction of welding progress than the first roller electrode (26). |
