PROBLEM TO BE SOLVED: To devise a method for temporary soldering capable of preventing opening in continuous friction stir joint without adversely affecting joint quality in the continuous friction stir welding. SOLUTION: In this method for temporary soldering by friction stir joint for friction stir joint of plate materials, the temporary soldering friction stir joint is conducted from the terminal end side of the continuous friction stir joint toward the start end side thereof, a jointing tool of the temporary soldering friction stir joint shall be the same jointing tool as the continuous friction stir joint, and a proceeding direction of the jointing tool in the temporary soldering friction stir joint shall be the same proceeding direction as that of the continuous friction stir joint. Since the starting point and the terminal point of the temporary soldering is the opposite to the starting point and the terminal point of the continuous friction stir joint, an expansion direction of a groove by the continuous friction stir joint is the opposite to the expansion direction by the temporary soldering friction stir joint, the expansion of the groove at the continuous friction stir joint is thereby controlled. |
