FRICTION STIR WELDING METHOD FOR LAMINATED METAL SHEET, AND METAL SHEET LAMINATE

PROBLEM TO BE SOLVED: To provide a friction stir welding method that enables lamination welding of not only two but three or more metal sheets and that can greatly reduce metallic flash of a weld zone to almost none, and to provide a laminated metal sheet body. SOLUTION: In the friction stir welding...

description PROBLEM TO BE SOLVED: To provide a friction stir welding method that enables lamination welding of not only two but three or more metal sheets and that can greatly reduce metallic flash of a weld zone to almost none, and to provide a laminated metal sheet body. SOLUTION: In the friction stir welding method for welding the same or different kinds of two or more metal sheets being laminated by FSPT (Friction Stir Processing Technique), a hole 9 for friction stir welding is formed which penetrates all layers of laminated metal sheets 8' before a friction stir process is performed. The friction stir process is performed by friction-stirring the laminated metal sheets with each other from inside the hole 9, by producing a frictional heat between the inner face of the hole 9 and a pin 12 of a friction stir welding tool 11 that is inserted into the hole.
