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. |
