摘要： A tool driving section of a friction stir spot welding device is configured to cause each of a pin member and a shoulder member to advance and retract, and is controlled by a tool driving control section. A press-fit reference point setting section sets a position where the pin member or the shoulder member contacts an object to be welded as a press-fit reference point, and the tool driving control section controls the position of the pin member with respect to the shoulder member on the basis of the press-fit reference point, thereby controlling the press-fit depth of a rotating tool press-fitted from the surface of the object to be welded. This achieves the excellent welding quality at suitable precision according to welding conditions especially in a double-acting friction stir spot welding method.
