Abstract: A method for counteracting tensile stress in an article is disclosed, including heating the article and applying compressive stress to the article along a compressive stress vector, the compressive stress vector including a compressive stress vector component opposite in direction to a tensile stress vector of a thermally-induced tensile stress of the article. The compressive stress is applied by thermally-induced autogenous pressure by a fixture contacting the article. A fixture for counteracting tensile stress is disclosed, including a first compression member and a second compression member, and a position lock connecting the first compression member to the second compression member and reversibly fixing the first compression member relative to the second compression member. The first compression member and the second compression member include compressive surfaces having mating conformations for surfaces of an article. The position lock includes a material composition.

Abstract: A method to repair an opening in a metallic device including: mount the device on a positioner; while the device is mounted on the positioner, sense and record positions of a surface of an opening in the device using a probe operated by a manipulator; based on the recorded positions determine a centerline and diameter of the opening; orient a digital model of the opening with respect to the opening of the device based on the centerline and diameter of the opening, and apply an weld or cladding to the opening by a welding torch maneuvered automatically by the manipulator while the device is mounted to the positioner and based on the oriented digital model of the opening.

Abstract: The present application provides a method of repairing a turbine blade. The method may include the steps of removing an existing tip cap from the turbine blade in whole or in part, machining the turbine blade to form a machined groove, positioning an insert in the machined groove, welding the insert to the turbine blade, and brazing the turbine blade.
