摘要：PROBLEM TO BE SOLVED: To further improve a service life of an electrode by suppressing expansion of a core material tip end in resistance welding using a dual structure electrode. SOLUTION: While an electrode body 3 is made of copper or a copper alloy, on its face in contact with a material to be welded, a core material 4 composed of W or Mo, or optionally an alloy having W or Mo as base materials is embedded in a dual structure electrode. Using this electrode, resistance welding is performed, wherein a welding current to be energized during the welding is made less than a current causing expulsion. COPYRIGHT: (C)2007,JPO&INPIT
