WIPO Patent Application WO/2004/020138

A1

A method of joining two metallic members of different melting points piled on each other, which enables obtaining stable joined part quality and enables junction of large metallic members of complex configuration. Two or more metallic members (aluminum member (101) and copper member (102)) are joined to each other through a process comprising arranging two or more metallic members (aluminum member (101) and copper member (102)) so that these are piled on each other in the order of highness of melting point and moving the circumferential face of tool main body (103a) of disk-shaped junction tool (103) capable of rotating in the circumferential direction, while in the piling portion pressing the same in the surface (102a) of metallic member (copper member (102)) having the highest melting point among those of the metallic members, along the surface (102a) of metallic member (copper member (102)).
