- 17 - ABSTRACT OF THE DISCLOSURE An electric resistance seam welding method and apparatus includes a continuous wire electrode which is passed successi- vely over a first electrode reel and thereafter over a second electrode reel via a plurality of guide and deflection rollers, the outer surfaces of the wire confronting each other when passing over the reels and being pressed together by the reels by a predetermined welding force against interposed workpieces to be seam welded together. An electric current is applied so as to pass from the second electrode reel to the first reel through the wire electrode and the interposed work- pieces, and the wire electrode is motor driven for feeding the workpieces through the reels. A copper wire is utilized as the wire electrode and has a tensile strength at the elastic limit of between 11 and 13 kg-f/mm2 and has a percentage elongation at break of 26 to 17 %. The reels are pressed to- gether by a force of 60 to 70 kg, and the copper wire is subject to a tensile stress of less than 10 kg-f/mm2 while passing over and between the reels. The reels are maintained at an operating temperature of 10 to 30° C as the wire elec- trode passes thereover, so that a maximum elongation of the wire of 6 % when passing over the first reel, and a maximum further elongation of the wire of 6 % when passing over the second reel, is attained.
