ABSTRACT:
The disclosure is concerned with a bonding method for bonding metallic members, which comprises the steps of: fitting a metallic members to another metallic member, followed by effecting preliminarily plastic bonding by means of a preliminarily bonding punch; and generating compression force in an axial direction of the members in the vicinity of the fitting portion of the bonding members after the preliminarily plastic bonding, and allowing part of the material of the bonding member to effect plastic-flow in such a manner as to fill a gap defined between the metallic members, so as to plastically bond the members; whereby the members are tightly integrated with each other.
