Reconstruction and Repair Services of Hot Section Parts of Gas Turbine by Welding and Recoating
Application:
Extracting thermal energy in the combustion chamber and transferring it to the shaft in the turbine
Product Introduction:
Due to being placed in the combustion chamber of gas turbines, this part is included in the classification of hot parts. Due to very specific working conditions due to high temperature and wear and also mechanical stresses on this part, the material, geometry and coating of these blades have a special and complex technology. The geometry and dimensions of these blades are very accurate and the specific curvature of each blade is determined by complex fluid and heat transfer calculations.

Application:
Cleaning and removing the coating |
Cleaning is usually done before the inspection and before and after the repair and reconstruction operation by two chemical and mechanical methods. |
Life estimation |
Estimating and increasing the life of gas turbine parts that are made of super alloy due to critical working conditions of high temperature and stress is very important, especially in the case that the turbine is opened and taken apart for periodic maintenance. |
Rejuvenation heat treatment |
By working the piece at high temperature, the dimensions and shapes of Γ' deposits change and also a brittle layer of carbides is created along the grain boundary, which will reduce the toughness and creep resistance. By increasing the temperature up to the dissolution temperature of the Γ ′ phase, these deposits return to their original state, and rapid cooling prevents the formation of Γ ′ deposits. |
Reconstruction by welding |
Welding is used to repair cracks. |
Reconstruction by brazing |
The advanced brazing method provides the possibility of rebuilding parts of the turbine that are not possible according to the usual methods. |
Coating |
If needed, the recoating of the blades should be done using hvof or aps processes. |
