The Transition Piece connects the combustion chamber to the turbine and acts as a nozzle that directs hot gases to the guide vanes of the turbine.
The TP is exposed to high thermal stress levels during operation, which makes it one of the most critical components of the entire engine. Therefore, it is coated with Thermal Barrier Coating (TBC), like the other combustion components.
Thorough grinding or grit blasting is essential prior to the maintenance process for both visual and red dye penetrant inspection to clearly identify the damaged areas. In addition to the cleaning and inspection processes, Aero Space Power performs TIG welding repair on certain areas. Due to the high heat exposure during welding, geometric control of the parts and taking other measurements require a great deal of expertise and practice.
