摘要

A welded structure and welding method make it possible to improve welding strength and welding quality. A welded structure in which a first member and a second member are joined by welding, wherein the first member comprises a second-member joining part which is joined to the second member, and the second member comprises a first-member joining part which is joined to the first member. If the direction in which the first member and the second member are arranged is the first direction, and the direction intersecting the first direction is the second direction, the welded structure comprises a cavity part which is provided between the first-member joining part and the second-member joining part, and a welded part which is provided between the cavity part and both end parts in the second direction of the joining surface where the first-member joining part and the second-member joining part are joined.
