TH55951B - Recovery method for damaged parts And recovery machine for the worn part - Google Patents

Abstract

DC60 (21/04/60) as the objective of the invention. This invention contains the preparation of the resuscitation method. For the damaged part Repairable And easily recovers the degraded parts that occur in metal assemblies. And reliably To reliably increase the service life of metal assemblies Especially The local heat stage of Dedicated Degradation C is done by the main heater 25 and the pressurized welding of the degreased part C by compression by thermal expansion. hot And the heating step along the perimeter of periphery heating And in the immediate vicinity of the HA1 heated area, in the local heating phase by the secondary heater 26, it was followed by a cooling stage of the receiving area. Heating HA1 is cooled by primary heater 25 and cooling the HA2 treated area by secondary heater 26 at the same time. Revised 04/21/2017 as the invention objective. This invention contains the preparation of the resuscitation method. For the damaged part Repairable And recover the deteriorated parts that occur in Easily assembled metal pieces And reliably To increase the service life of metal components That can be reliably longer Especially Local heating step of the Heats the deterioration C, especially by the main heater 25 and power welding. Press the degenerate part C by compression by thermal expansion. And the heating process according to Perimeter of peripheral heating And in the immediate vicinity of the HA1 heated area, in the local heating phase by the secondary heater 26, it was followed by a cooling stage of the receiving area. Heating HA1 is cooled by primary heater 25 and cooling the HA2 heated area by secondary heater 26 at the same time. --------------------- as the objective of the invention This invention contains the preparation of the resuscitation method. For the damaged part Repairable And recover the deteriorated parts that occur in the pieces Easily assembled metal And reliably To increase the service life of the metal components More reliably Especially Local heat stage of heating Dedicated C degradation section by main heater 25 and pressure welding Deteriorate C by compression by thermal expansion And the process of heating along the line Periphery of peripheral heating And in the immediate vicinity of the HA1 heated area in the local heating phase by the secondary heater 26 has been performed, followed by a cooling stage of the receiving area. Heating HA1 is cooled by primary heater 25 and cooling the HA2 heated area by secondary heater 26 at the same time.

Claims (9)

1.
