Advanced Repair Development in Stationary Gas Turbine Combustion Components

Abstract This article describes advanced techniques used in the repair and refurbishment of a platform combustion system (PCS) for an SGT5-8000H turbine. The first part outlines the refurbishment process of the part basket—a key PCS component—covering inspection, repair, recoating, and final assembly steps. The second part highlights the integration of advanced repair technologies, including laser-based cutting and welding, as well as patch repairs using 3D-printed parts via laser powder bed fusion.
