Abstract: A method for forming or remanufacturing a component to have an internal space. A refractory metal blocking element is formed, in situ, with at least a portion to be within the internal space. The formation includes an at least partial melting. A material is added, the blocking element at least partially blocking entry of the material to the internal space. The blocking element is removed.

Abstract: A method for repairing a gas turbine engine component includes the steps of repairing one of a suction side or a pressure side of the component; repairing internal geometry of the component after one of the suction side or the pressure side of the component is repaired; and repairing the other of the suction side and the pressure side of the component after the internal geometry of the component is repaired, wherein a backing material is utilized to preserve the internal geometry of the component when the other of the suction side and the pressure side of the component is being repaired.
