摘要： PROBLEM TO BE SOLVED: To provide a method of repairing by build-up welding so that a hot crack is not more than the allowable defect even when required allowable defect is small and welding material having the same strength as a base metal is used.
SOLUTION: A gas turbine member is repaired by performing regular build-up welding after removing the damaged portion of the base metal 1 and forming an intermediate layer 4 in the part to be removed where the damaged portion is removed. By providing a process for forming the intermediate layer 4 before the regular build-up welding, heat input to the base metal 1 during the regular build-up welding is reduced.
