    • In a method for electrical resistance roll seam welding with a single electrode-wire, wherein the electrode-wire runs over first and second electrode carrier-rolls urged against each other, and the strength of the electrode-wire is increased by rolling-out before it enters the first electrode carrier-roll, elongations of the electrode-wire which can otherwise arise and lead to a slippage of the electrode-wire at the welding point and therefore, deleteriously affect the weld-quality can be largely prevented by reducing the electrode-wire temperature at the welding-point by cooling with a cooling device (17) the electrode-wire (12) between its rolling-out point (17/18) and its passage onto the first electrode carrier-roll (14) and/or between its departure from electrode carrier-roll (14) and its passage onto the second electrode carrier-roll (15).
    • 在用单电极线进行电阻辊缝焊接的方法中,其中电极线在彼此推压的第一和第二电极载体辊之间延伸,并且电极丝的强度通过在 它进入第一电极载体辊,否则可能出现的电极线的伸长并导致焊点处电极丝的滑动,因此可以通过减少电极来极大地防止焊接质量的有害影响 通过用冷却装置(17)将电极线(12)冷却在其熔点处,该电极线(12)在其滚出点(17/18)及其通向第一电极载体辊(14)和/ 或者在其离开电极载体辊(14)和其通向第二电极载体辊(15)之间。
