US 2016/0243655 A1 · COMPONENT REPAIR USING CONFINED LASER DRILLING

Abstract

A method for repairing one or more holes in a near wall of a component is provided. The method includes determining updated hole information, including an updated location, of a first hole in the near wall of the component. The method also includes directing a confined laser beam of the confined laser drill towards the near wall of the component at the updated location of the first hole to drill through a coating of the component extending over and/or positioned in the first hole. The method also includes sensing a characteristic of light reflected from the updated location of the first hole and determining the confined laser beam of the confined laser drill has drilled through a portion of the coating of the component extending over and/or positioned in the first hole based on the sensed characteristic of light.
