Welded construction and resistance welding method

摘要

A welded construction according to the present invention has a first metallic member 110, on one surface of which a projecting portion 112 is formed and on the other surface of which a depressed portion 111 corresponding to the projecting portion 112 is formed, and a second metallic member 120 are welded together at a welded portion 130 which includes a summit portion of the projecting portion 112; wherein, on at least one of the first metallic member 110 and the second metallic member 120, on its opposite surface to its surface that faces the other one of the metallic members, a recessed portion 113 is formed that is recessed from its peripheral region towards a region which corresponds to the welded portion 130.
