ELECTROMAGNETIC-FORMING METHOD OF METAL MEMBER FOR BONDING, METAL MEMBER FOR BONDING, AND JOINT FOR METAL MEMBER

摘要

PPROBLEM TO BE SOLVED: To provide a metal member forming method for forming a flange having a shape corresponding to the shape of an outer surface of a counter member to be bonded at an end of the metal member by an electromagnetic-forming method, and to provide a metal member for bonding, and a joint therefor. PSOLUTION: In the metal member electromagnetic-forming method, an end of a metal member 1 is deformed by electromagnetic forming, an outer surface of the deformed end is pressed against a die forming face 4, a flange 2 of the predetermined shape is formed on the end of the metal member 1, and the flange portion is work-hardened.
