<P>PROBLEM TO BE SOLVED: To provide a joining method of different metals for efficiently forming a sound joined section having small strain and defect and high joining strength, and a joined matter having the sound joined section having small strain and defect and high joining strength. <P>SOLUTION: This joining method of different metals is a joining method of directly laser-joining, with a predetermined joint, a first member and second member made of metals having a surface to be joined without inclusion. In this joining method, an adhesion surface is performed by sticking the surface to be joined of the first member whose laser absorptance and melting point for laser are lower than those of the second member to the surface to be joined of the second member, and laser is irradiated simultaneously to adjacent regions on both surfaces gripping the adhesion surface. <P>COPYRIGHT: (C)2012,JPO&INPIT |
