A

To obtain a method for repairing a rotor and a device for repairing a rotor where the damage of a rotor can be repaired in such a manner that thermal damage to a rotor base material is reduced, and the reduction of the period for periodical inspection and the reduction of repairing cost can be attained.

In the stage S1, the damaged location to be repaired in a rotor 1 is subjected to removing and shaping by machining or grinder working. In the stage S2, the surface from which the damaged location to be repaired is removed and shaped by machining or grinder working is subjected to roughening by blast treatment. In the stage S3, a film is formed on the surface roughened in the stage S2 by a high speed flame spraying device. In the stage S4, the film formed in the stage S3 is subjected to finishing treatment by machining or polishing. In the stage S5, defect inspection is performed for inspecting whether defects or the like are present or not. In the stage S6, inspection for the dimensions and quality of the location repaired in the stage S6 is performed.
