<p>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 (1,2,3) 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 (1), a zinc plated steel plate (2) and a bare steel plate (3), for example, are layered in order. A nugget (Ns) 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 (Nd) is formed in an interface between the aluminum alloy plate and the zinc plated steel plate.</p> |
