  • Gas turbine blade having a monocrystalline airfoil with a repair squealer tip, and repair method
    Patent number: 7278829
    Abstract: A repaired gas turbine blade includes a turbine blade body having a monocrystalline airfoil made of a first nickel-base superalloy, and a repair squealer tip welded to a tip of the airfoil. The repair squealer tip is made of a second nickel-base superalloy different from the first nickel-base superalloy and having less than about 0.15 weight percent total of carbon, boron, silicon, zirconium, and hafnium.
    Type: Grant
    Filed: February 9, 2005
    Date of Patent: October 9, 2007
    Assignee: General Electric Company
    Inventors: Lawrence Joseph Roedl, Rabon Hensley

  • Heating apparatus for a welding operation and method therefor
    Patent number: 6583387
    Abstract: A heating apparatus and method for pre-weld heat treating, welding and post-weld heat treating a superalloy article in a single enclosure while avoiding oxidation of the article. The enclosure is preferably equipped with a one-way valve that permits the escape of gases, but otherwise seals the enclosure to prevent the ingress of air during welding and heat treatment as a result of thermal gradients induced when the article is inductively heated. To provide access to the article and a device used to weld the article, the enclosure is equipped with gloves by which the welding device and the article can be manipulated while a nonreactive atmosphere is fully maintained within the enclosure and the article is inductively heating.
