Abstract: An example method of repairing an airfoil includes the steps of securing additional material to a worn airfoil and limiting movement of the additional material with a guide.

Abstract: Methods for performing manual laser deposition are provided. In this regard, a representative method includes: directing a laser beam at a first deposit location of a substrate to re-melt: at least a portion of a first deposit of weld filler, at least a portion of a second deposit of weld filler located at a second deposit location that partially overlaps the first deposit, and at least a portion of the substrate.

Abstract: A process for repairing cracks in a workpiece, such as a turbine engine component, comprises the steps of: providing a workpiece having a crack to be repaired; applying a nickel or cobalt base alloy material to a root of the crack in an amount sufficient to fill a portion of the crack; subjecting the workpiece with the nickel or cobalt base alloy material to a first heat treatment at a temperature in the range of from about 1950 to 2300° F. for a time period in the range of from about 5.0 to 30 minutes; applying a weld material to the crack; and subjecting the workpiece with the weld material to a second heat treatment.

Abstract: A method of restoring a stator inner shroud comprising manually feeding successive portions of a filler material to a damaged region in a surface of the stator inner shroud and laser welding the damaged portion.

Abstract: A first component is bulk brazed to a second component. The bulk braze joint is inspected. Responsive to the inspection locating a defect site, the joint is laser brazed at the defect site.

Abstract: A method of repairing a braze joint and the resulting joint includes removing an unsuitable portion of a first joining material in a joint between a first member and a second member of an aerospace assembly and cleaning the joint. A stripping solution is used to remove the unsuitable portion of the first joining material. A first cleaning solution is used to clean the joint, and the joint is further cleaned using a second cleaning solution. During a rebrazing step, a second joining material moves into a void left by the removed unsuitable portion from the removal step to form a new joint between the first member and the second member that includes the remaining first joining material and the second joining material.

Abstract: Brazed structures comprising hollow components having a closure component bonded thereto by a metallic brazing alloy for closing off an end of the hollow component are disassembled by locating a wire transport material in the hollow component and covering the open face of the hollow component with a wire fiber material. Heat is then applied to liquefy the brazing alloy which is drawn up into the metal wire fiber material by capillary affect created by the wire transport material.
