摘要：
A method and apparatus for resistance welding in which, while both or one of the electrode center axes of a pair of opposing electrodes is inclined with respect to the electrode forcing axis, the electrode tip of the electrode is intermittently pivoted about the electrode center axis for welding. The contact between the electrode tip and workpiece is moved at a preset number of welds to define a next contact surface on the face of the electrode tip, and thus the number of welds (electrode tip life) is considerably improved.
