金属材の接合方法及び金属接合体
Document Type and Number:
Japanese Patent JP7264406
Kind Code:
B2
Abstract:
Provided is a simple method for firmly joining metal materials in various combinations of similar types of metals and different types of metals, wherein the joining method makes it possible to suppress electrolytic corrosion of a joining part in a case where metals of different types are joined. Also provided is a metal joining body having a joining part that has high joining strength such that a joint extends to a metal part in a tension test, the metal joining body being such that electrolytic corrosion of the joining part is very effectively suppressed. This method for joining metal materials is characterized by having: a first step in which one metal material and another metal material are brought into contact with a resin layer interposed therebetween, thus forming a joining interface; and a second step in which the surface of the one metal material and/or the other metal material is irradiated with a laser, the one metal material is joined to the resin layer at the joining interface, and the other metal is joined to the resin layer, thus forming the joining part.
