To provide a novel vehicular door sash seam-welding method by which, for example, strain due to weld heat can be reduced.SOLUTION: According to this method, seam-welding is performed in such a manner that a connection part 9c of an upper sash 9 is sandwiched by a first roller electrode 415 having plural first protrusions 415a and second protrusions 415b which are spaced from each other in a circumferential direction around a first rotation center C1 and a second roller electrode 416 having plural first facing protrusions 416a and second facing protrusions 416b which are separated from each other in a circumferential direction about a second rotation center C2, and is electrically conducted while being rotated.SELECTED DRAWING: Figure 7

    【課題】例えば、溶接熱によるひずみを軽減することが可能な新規な車両用ドアサッシュの溶接方法を得る。【解決手段】第一回転中心C1回りの周方向に間隔をあけた複数の第一凸部415aおよび第二凸部415bを有した第一ローラ電極415と、第二回転中心C2回りの周方向に間隔をあけた複数の第一対向凸部416aおよび第二対向凸部416bを有した第二ローラ電極416と、によってアッパーサッシュ9の連結部9cを挟持し回転しつつ通電することでシーム溶接を行う。【選択図】図7
