    Abstract: A fixture and method for resistance welding of at least one pad to at least one surface of an article is disclosed. The method includes mounting the article in the fixture, placing the at least one pad on the at least one surface of the article, positioning a first electrode of a resistance welding apparatus to the at least one pad and a second electrode of the resistance welding apparatus to the article, and applying pressure and electric current across the at least one pad and the at least one surface. The fixture includes a first, second and third support element, which, respectively, include a first, second and third contact surface being adapted and disposed to support a first, second and third portion of the article. The first, second and third contact surfaces are each inelastic and electrically insulating. The fixture is arranged and disposed to non-rotatably cradle the article.

    Abstract: A method of welding a superalloy component includes the following sequential steps. A welding step for welding a cavity using a filler metal in an inert atmosphere, where the cavity is located in the component. A covering step for covering the filler metal and a portion of the component with a weld filler layer in the inert atmosphere. The weld filler layer has a greater ductility than material comprising the component and/or material comprising the filler metal. A second covering step for covering the weld filler layer with a braze material, and subsequently performing a brazing operation. A heat treating step heat treats the component.

    Abstract: A method of repairing a superalloy component includes subjecting the superalloy component, including a repair area, to a phase agglomeration cycle, which includes stepped heating and controlled cooling of the component. The method further includes applying weld material to the repair area to create a weld surface; and covering the weld surface with brazing material. The component is then subjected to a braze cycle to produce a brazed component. The brazed component is cleaned, and the cleaned component is subjected to a restorative heat treatment to restore the microcrystalline structure and mechanical properties of the component.
