Document Type and Number:
Japanese Patent JP7010767
Kind Code:
B2
Abstract:
To provide a manufacturing method of a welded structure and the welded structure capable of manufacturing the welded structure having improved fatigue strength of a forming part which is formed on base metal according to lamination forming.SOLUTION: A manufacturing method of a welded structure of manufacturing the welded structure W which forms a forming part 53 on the surface 55 of base metal 51 includes a lamination process of forming a laminate part 57 which becomes the forming part 53 by laminating weld beads 61 provided by melting and solidifying filler material M onto the surface 55 of the base metal 51 in layers and a cutting process of cutting the laminate part 57 to work the laminate part into the forming part 53. Therein, in the lamination process, when forming the weld beads 61 of at least the undermost layer, on the outer side of a joint area of the base metal 51 to which the forming part 53 is joined, weld bead 61a for heat input which is caused to continue with the weld beads 61 becoming the forming part 53 and does not become the forming part 53 is formed and, on the cutting process, the weld bead 61a for heat input is cut and removed.SELECTED DRAWING: Figure 1
