DETERIORATED PORTION REPRODUCING METHOD AND DETERIORATED PORTION REPRODUCING DEVICE

摘要

An object is to provide a deteriorated portion reproducing method and a deteriorated portion reproducing device for easily and certainly repairing and reproducing a deteriorated portion generated in a metal member and certainly extending the life of the metal member. A local heating process for locally heating a deteriorated portion (C) using a main heater (25) and allowing the deteriorated portion (C) to be pressure-welded using compression force generated by heat expansion and a periphery heating process for heating the neighborhood of the periphery of a region (HA1) heated in the local heating process using a sub heater (26) are performed. Then, a cooling process for simultaneously cooling the region (HA1) heated by use of the main heater (25) and a region (HA2) heated by use of the sub heater (26) is performed.
