摘要：
The present invention has as its object the provision of a restoration method for a deteriorated part, which is capable of easily and reliably repairing and restoring a deteriorated part generated in a metal member to reliably prolong the lifetime of the metal member. Specifically, a local heating step of locally heating a deteriorated part C by a main heater 25 and pressure-welding the deteriorated part C by a compression force by thermal expansion and a peripheral heating step of heating the periphery and vicinity of a heated region HA1 in the local heating step by a sub heater 26 are carried out, followed by carrying out a cooling step of cooling the heated region HA1 by the main heater 25 and a heated region HA2 by the sub heater 26 at the same time.
