摘要： PROBLEM TO BE SOLVED: To provide an electrode for projection welding capable of reducing defective projection welding and abnormal wear of a projection for projection welding.
SOLUTION: Recesses 14 for accommodating raised portions 41, 42 generated on peripheral edges of recesses 31, 32 of projections 110, 120 for projection welding are formed in respective centers of conductive faces 50 of electrodes 12, 13 for projection welding. The respective conductive faces 50 of the electrodes 12, 13 for projection welding are uniformly brought into contact with a non-welding side main surface 22 of a plate 2 as a workpiece, and defective welding is reduced, and the lifetime of the welding electrodes can be considerably prolonged.
