  • Method of repairing the turbine airfoil nozzle segment
    Publication number: 20070184182
    Abstract: A trailing edge coupon for the trailing edge of a airfoil of a turbine nozzle segment is welded to an airfoil section of the nozzle segment having a damaged trailing edge portion removed. The coupon includes film cooling holes spaced one from the other along a pressure side wall portion of the coupon and a plurality of radially spaced openings along the trailing edge. By welding the pressure and suction side edges of the coupon to the pressure and side edges of the remaining portion of the airfoil, the operating life of the nozzle is extended.
    Type: Application
    Filed: March 21, 2007
    Publication date: August 9, 2007
    Applicant: General Electric Company
