Abstract

A welded structure provided with a fillet welded joint in which an end face of a joining member (1) is butted against a front face of a joined member (2) having a plate-thickness of 50 mm or more, the joining member (1) and the joined member (2) being joined by the fillet weld joint, where a weld leg length (3) and a welding width (13) of the fillet weld joint are more than 16 mm; an unwelded portion (4) is included at a butting face between the end face of joining member (1) and the front face of the joined member (2) in the fillet weld joint, the unwelded portion (4) being 95 pcnt or more of a plate thickness (tw) of the joining member (1) in a cross section of the fillet weld joint; and further, for a fillet weld metal (5) in the fillet welded joint, a Charpy impact test fracture appearance transition temperature (vTrs (øC)) of the fillet weld metal (5) and a plate thickness (tf) of the joined member (2), and optionally the smaller value (L) of the weld leg length (3) and the welding width (13), satisfy a predetermined relationship.
