Abstract: A method of repairing a component using an additive manufacturing process is presented. The method includes submerging the component into a powder bed so that a portion of the component to be repaired is level with a surface of the powder bed and a protruding portion of the component protrudes above the surface of the powder bed, positioning a split wiper that includes a first wiper segment and a second wiper segment in the powder bed at the surface, advancing a quantity of powder by translating the first wiper segment and the second wiper segment across the surface of the powder bed, and directing a laser beam across the surface to fuse powder particles of the powder bed to the underlying substrate forming a layer of the component. Each of the first wiper segment and the second wiper segment follow a different contour of the protruding portion at the surface.

Abstract: Methods for direct writing of single crystal super alloys and metals are provided. The method can include: heating a substrate positioned on a base plate to a predetermined temperature using a first heater; using a laser to form a melt pool on a surface of the substrate; introducing a superalloy powder to the melt pool; measuring the temperature of the melt pool; receiving the temperature measured at a controller; and using an auxiliary heat source in communication with the controller to adjust the temperature of the melt pool. The predetermined temperature is below the substrate's melting point. The laser and the base plate are movable relative to each other, with the laser being used for direct metal deposition. An apparatus is also generally provided for direct writing of single crystal super alloys and metals.

Abstract: A method to repair a turbomachine including: assign blades and a shroud in a row of the turbomachine to a group; measure, for each blade in the group, a clearance between a tip surface of the blade and a surface of the shroud facing the tip surface; remove the blades and shroud from the row; calculate a difference between the clearance of associated each blade and a design clearance; determine, for each blade, if the difference may be minimized by adding material to the surface of the shroud; adding material to the surface of the shroud, wherein the addition of material to the facing surfaces results in the shroud having at least one dimension that exceeds an original design dimension of the shroud sections, and installing the group of the blades and the shroud with the added material to a row of a turbomachine, wherein at least one of the blades has at least one dimension that does not conform to an original design specification for the blade.
