Zusammenfassung:A method for repairing a blade (10) for use in a gas turbine engine, the method comprising removing a distal tip of an airfoil (16) included in the blade (10) to remove damaged portions of the airfoil and to expose previously internal cooling passages. The method further comprising positioning a tip cap (24) in the place of the removed distal tip to cover the internal cooling passages, and welding the tip cap (24) to the airfoil by applying a directed energy beam onto the tip cap (24) and the airfoil (16) at a joint between the tip cap (24) and the airfoil (16).
