"Turbine Blade Repair" A method of repairing a turbine blade (10) comprises removing damaged material (22) from an area (30) to be repaired, applying by welding a layer of a first material in the form of a soft metal (31) such as Inconel and subsequently applying a layer of second material in the form of a hard metal (36) such as Stellite, the blade may then be worked by machining, grinding or polishing to the desired profile (35,40) and subjected to a heat treatment process for stress relief. The repair method enables a fast repair that can be carried out without the blade (10) being removed from the rotor (13) or stator and which is economical in use of materials.
