Abstract

A repair system for a part (1340) for a gas turbine engine includes a deposition system (1308) that implements a friction stir additive manufacturing (FSAM) process. An inspection system coupled to the repair system identifies a region of interest having damage on the part (1340). A process for deposition of metallic deposition material onto the region of interest performed using the deposition system (1308). A rod (1324) of the metallic deposition material is moved using pressure exerted within the deposition system (1308) into a deposition zone (1328) of the region of interest. The region of interest is pre-heated prior to the pressure being exerted. Frictional heat is generated when the rod (1324) contacts the deposition zone (1328). Parameters to control the components within the deposition system (1308) are determined using a function and a depth of the layers (1346) of the metallic deposition material determined for enabling the repair process.
