摘要:
Disclosed is a bonding method for dissimilar materials made from metals and its resulting structures. The materials to be bonded are formed by layering three or more sheets such that a dissimilar material interface and a same material interface are formed. A first current is conducted between a three-sheet layered plate material wherein an aluminum alloy plate, a zinc plated steel plate and a bare steel plate, for example, are layered in order. A nugget is formed in an interface between the zinc plated steel plate and the bare steel plate, which are the same materials. Then, a second current greater than the first current is conducted, and a nugget is formed in an interface between the aluminum alloy plate and the zinc plated steel plate.

According to a metal joining method of the present invention, first and second dissimilar metals are joined together by interposing between the first and second metal materials a third metal material dissimilar to the first and second metal materials and causing eutectic melting at least either at an interface between the first and third metal materials or at an interface between the second and third metal materials.
摘要:
A method of joining dissimilar materials of the present invention has a step of lapping a high melting point material on a low melting point material with a third material interposed therebetween. The third material is different from the high and low melting point materials. Further, the method has a step of irradiating an energy beam onto the high melting point material and a step of pressing the high and low melting point materials to cause eutectic melting between at least one of the high and low melting point materials and the third material and to join the high and low melting point materials in the form of a line.
