Abstract: A method for forming or remanufacturing a component (22; 200) to have an internal space (50). A refractory metal blocking element is formed, in situ, with at least a portion to be within the internal space (50). A material (90; 232) is added by at least one of welding, laser cladding, and diffusion brazing, the blocking element at least partially blocking entry of the material (90; 232) to the internal space (50). The blocking element is removed.

Abstract: A method for forming or remanufacturing a component (22) to have an internal space. A refractory metal blocking element (100; 152, 154) is positioned with at least a portion (104; 156) to be within the internal space. A material is added by at least one of laser cladding and diffusion brazing, the blocking element (100; 152, 154) at least partially blocking entry of the material to the internal space. The blocking element (100; 152, 154) is removed.

Abstract: The present invention relates to a method for repairing components such as blades used in turbine engines. The method comprises the steps of placing a piece of refractory metal material (16) over an area of the component to be repaired (12) and depositing a repair filler metal material (20) over the piece of refractory material (16) in an amount sufficient to repair the component and welding the repair filler metal material (20) in place. The refractory metal material (16) may be selected from the group consisting of niobium, tantalum, molybdenum, tungsten, a metal having a melting point higher than the melting point of nickel, and alloys thereof and may be uncoated or coated.
