摘要： PROBLEM TO BE SOLVED: To provide a method for welding a weld structure, by which residual stress is changed into compressive stress by executing the treatment for improving the residual stress in the welded surface of the weld structure.
SOLUTION: The objective of the method for welding is a reactor core shroud 10, which is installed inside a reactor pressure vessel and surrounds a reactor core, piping or a vessel. The welding method for the reactor core shroud 10 is used for setting a new reactor core shroud 11 on a base reactor core shroud 12 by on-site welding when installing the reactor core shroud 10 to be welded. In the welding method for the reactor core shroud 10, after the new core shroud 11 is placed on the base core shroud 12, weld bead sequences 15 are sequentially formed by performing build-up welding of weld beads 16 by a plurality of passes from the outer or inner surface side of the shroud toward the reverse surface side thereof. In the formation of the weld bead sequences 15, welding conditions are selected according to the weld positions in the radial direction of the shroud so that the residual stress in the surface of the shroud becomes a compressive stress.
