Abstract
A one-side spot welding method for causing an electrode to contact a welding portion of a work-piece only from one side of the work-piece to weld the work-piece, the method includes a nugget forming process of applying welding pressure to the work-piece through the electrode, and causing the work-piece to be fully electrically conducted at a predetermined current value, and a slow-cooling process of applying welding pressure to the work-piece through the electrode from the one side, and causing the work-piece to be electrically conducted at a current value lower than the predetermined current value after the nugget forming process.
