<P>PROBLEM TO BE SOLVED: To solve the following problem of a conventional pulse electric-current bonding method: when a joint surface is parallel (or oblique) to a pressure-application direction, the adhesion of the joint surface is deteriorated to reduce the joint strength. <P>SOLUTION: A pressure surface of a first metal material for receiving a pressure therethrough is fabricated to have a parallel component and a vertical component relative to a pressure-application direction, and an electrically-conductive core is fabricated to have a surface along the pressure surface and a surface vertical to the pressure-application direction. The first metal material, a second metal material and the core are set in the pulse electric-current bonding apparatus to perform a pulse electric-current bonding. <P>COPYRIGHT: (C)2012,JPO&INPIT |
