  • Weld fixture and method for repairing annular components
    Patent number: 6607114
    Abstract: A multifunctional weld fixture is provided having a base receiving a component and a plurality of locator tabs disposed around its outer edge. A circumferential array of expansion feet are movably attached to the top surface of the base. A disk-shaped wedge is disposed in sliding engagement with the expansion feet. A cover supports a portion of the component and seals against the component to create an enclosed plenum. The same fixture may be used to expand the component to compensate for shrinkage after the weld is compete.
    Type: Grant

    Date of Patent: August 19, 2003
    Assignee: General Electric Company
    Inventors: David T. Reser, Robert Dale Lawrence, Michael Paul Cook, Larry Dean Brock, David John Dietz
  • Restoration of thickness to load-bearing gas turbine engine components
    Patent number: 6571472
    Abstract: A method for restoring thickness to load-bearing components of gas turbine engines, and for repairing a honeycomb structured gas turbine engine component. A surface of the component such as the backing surface of a honeycomb component after honeycomb removal is roughened and cleaned. A selected build-up material is deposited onto the substrate by high velocity oxy-fuel deposition or low pressure plasma spray. The component is heat treated to enhance the bond between the deposited material particles, and between the deposited material and the substrate by diffusion.
