ABSTRACT:
A method for electromagnetically forming a metallic member includes deforming an end of a metallic member by electromagnetic forming, pressing the outer surface of the deformed end on the surface of a mold to form a flange having a predetermined shape at the end of the metallic member and, at the same time, work-harden the flange. The method is capable of forming a flange having a shape corresponding to the shape of the outer surface of another member to be joined to the metallic member at an end of the metallic member with high dimensional accuracy and shape accuracy and secured joint strength.
