摘要： A pair of upper and lower electrode wheels (1, 2) are disposed so that their axes (17, 18) are tilted in a horizontal plane in respective directions opposite to each other with respect to a straight line (Y) perpendicular to a welding line (X) defined on overlapping portions (L) of two metal plates (5, 6), and mash seam welding is performed while positively driving electric motors (61, 62). This can reduce the increased amount of thickness and step gradient of a joint portion to reduce a stress concentration factor to ensure a high degree of joint strength. The metal plates are joined to each other such that a nugget (N) is not deviated from a joint interface. The respective tilting directions of the axes (17, 18) of the electrode wheels (1, 2) are made to face in the horizontal plane toward the extending direction of a metal plate with which the electrode wheels (1, 2) first come into contact. Therefore, it is possible to prevent respective ends of the metal plates at the overlapping portions L from biting into and scratching the corresponding electrode wheels (1, 2) and to prevent the occurrence of spattering during the welding.
摘要翻译：一对上，下电极轮（1,2）被布置成使得它们的轴线（17,18）相对于垂直于焊接的直线（Y）在彼此相反的方向上在水平面内倾斜（5）的重叠部分（L）上限定线（X），并且在正向驱动电动机（61,62）的同时执行压薄滚缝焊接。这可以减小接头部分的增加的厚度和阶梯度，以减小应力集中系数以确保高度的接合强度。金属板彼此接合，使得熔核（N）不会从接合界面偏离。使电极轮（1,2）的轴（17,18）的各个倾斜方向朝向水平面朝向电极轮（1,2）首先进入的金属板的延伸方向联系。因此，可以防止重叠部分L处的金属板的相应端部咬入并刮擦相应的电极轮（1,2），并防止在焊接期间发生飞溅。
