Zusammenfassung:	An apparatus and a method for repairing a component (100) of a gas turbine engine is provided. The method includes locating a damaged area (108,110) of the component, preparing a portion of the component that includes the damaged area leaving a remaining portion of the component, welding at least one layer of material to the remaining portion (120), using a cold metal transfer (CMT) process, and removing excess material from the component to a predetermined dimension.
