<P>PROBLEM TO BE SOLVED: To provide a welded structure in which the propagation of a brittle crack is stopped, where, even in case the brittle crack is generated, before it reaches a large-scale rupture, the propagation is stopped by simple working without using a high-cost arrester material largely comprising alloys. <P>SOLUTION: Regarding the welded structure provided with a joined plate 2 obtained by joining two metal plates 2a by welding and a plate 4 to be joined to the joined plate 2 by welding, and in which a welding joint part 6 between the two metal plates 2a elongates to the vicinity of the joining position of the joined plate 2 and the plate 4 to be joined toward the plate 4 to be joined, in the direction to which the welding joint part 6 goes to the plate 4 to be joined, the welding joint part 6 and the plate 4 to be joined are not contacted, and further, a weld zone of joining the joined plate 2 and the plate 4 to be joined does not exist between the welding joint part 6 and the plate 4 to be joined. <P>COPYRIGHT: (C)2012,JPO&INPIT |
