Abstract

A method of repairing a part (100') with a directed energy deposition (DED) repair operation includes identifying a repair zone (108') on the part (100'). The repair zone (108') represents a region that includes at least one zone of operational wear or damage requiring the DED repair operation. A layer of repair material is applied to the repair zone (108') and the repair zone (108') is preheated using a first energy source (110b'). The layer of repair material in the repair zone (108') is melted using a second energy source (110') and is permitted to cool and solidify. The applying, preheating, melting, and cooling steps are repeated a desired number of times to accomplish the desired repair. Use of the first energy source (110b') and the second energy source (110') results in a temperature-affected zone (116') that does not extend beyond the repair zone (108') such that heat-sensitive portions of the part (100') do not experience distortion that exceeds allowable tolerances.
