Beschreibung
Zusammenfassung:	The present invention provides an apparatus for repairing turbine blades of a gas turbine engine by a laser welding operation. The method uses a miniaturized laser and related apparatus. The miniaturized laser is fed through a borescope access hole to a desired location such as a high pressure turbine blade. The laser is then powered and manipulated so as to perform the desired welding operation. Filler material may also be provided in situ to accomplish the welding procedure. The method realizes a significant cost savings to the vehicle operator in that repairs can be accomplished without the need to remove the engine or disassemble the engine.
