Abstract

This welded structure comprises a fillet welded joint which joins a joining member (1) and a joined member (2) having a plate-thickness of 50 mm or larger, in which an end face of the joining member (1) is in contact with a surface of the joined member (2). The weld leg length (3) and the welding width (13) of the fillet welded joint are each larger than 16 mm. A surface of the fillet welded joint at which the end face of the joining member (1) is in contact with the surface of the joined member (2) includes a non-welded part (4) at which the cross section of the fillet welded joint is not smaller than 95 pcnt of the plate-thickness (tw) of the joining member (1). Further, regarding a fillet welded metal (5) of the fillet welded joint, a predetermined relationship is satisfied between the Charpy impact test fracture transition temperature (vTrs (oC)) of the fillet welded metal (5) and the plate-thickness (tf) of the joined member (2), or among the temperature (vTrs (oC)), the thickness (tf), and a value (L) which is the lower between the weld leg length (3) and the welding width (13).
