摘要

本发明之课题在于获得一种可得到充分的接合强度，且可防止接合时产生之熔融物的飞散的覆层金属与金属零件的接合方法。;覆层金属与金属零件的接合方法系具有：准备本体具有孔之覆层金属的步骤；准备金属零件的步骤，该金属零件系具有比覆层金属的孔为更大直径之突起部，并且在该突起部的前端具有比开设于覆层金属的孔径为更大直径的孔；及将设置于金属零件之突起部的孔抵接于设置于覆层金属的孔而进行熔接的步骤。;The joining method for joining clad metal and metal parts comprises: a step of preparing a clad metal having a hole in a body; a step of preparing a metal parts having a protrusion, which has a greater diameter than the hole of the clad metal, and, at the front of the protrusion, having a hole with a greater diameter than the hole provided on the clad metal; and a step of putting the hole provided at the protrusion of the metal parts against the hole provided on the clad metal so as to perform the joining.
