Summary:PURPOSE:To easily obtain desired temperature and to easily carry out reforming by repeating energizing and unenergizing in heat-treating a heat-affected zone. CONSTITUTION:In the aftertreating method of spot welding in which an electrode after welding is reenergized, works are heated by joule heat and the heat-affected zone, etc., are subjected to softening treatment, this softening treatment is carried out by repeating energizing and unenergizing periodically.
