Title: Friction stir welding method for different kinds of metallic materials
Inventor: NAKADA KAZUHIRO
IPC: B23K20/26
Filed: 2001-03-22
Abstract: PROBLEM TO BE SOLVED: To provide a friction stir welding method in which metallic workpieces having a mutually different deformation resistance (strength) can be welded to each other with improved quality. SOLUTION: A workpiece with a large deformation resistance is heated while one with a small deformation resistance is cooled as necessary, so that both workpieces are then friction-stir welded. In this case, the workpiece with a large deformation resistance is heated and held in the manner that its tensile strength at the time of welding is not less than the yield strength of the workpiece with a small deformation resistance at room temperature and not more than 120% of the maximum (ultimate) tensile strength. Meantime, the workpiece with a small deformation resistance is cooled so that either its yield strength or tensile strength is maintained at its 80% value or above at room temperature.
