Abstract:
A method for disposing a region of material at a shroud face location for a rotor blade, the rotor blade having a root section, a platform section, an airfoil section extending spanwisely outwardly from the root section, a shroud section extending laterally with respect to the airfoil, the shroud section being formed of a first material and having a shroud face location and a substrate for receiving a material and having a flow path surface which faces the platform section of the airfoil, comprising:forming a pool of molten material adjacent the substrate by melting material at the substrate location on the shroud which includes flowing a portion of molten material toward the flowpath surface of the shroud;blocking the flow of molten material to the flow path surface of the shroud by urging a pad against the flow path surface of the shroud which closely conforms to the contour of the flow path surface;cooling the molten material and shroud while urging the pad against the flow path surface of the shroud to contact at least part of the molten material and until the molten material is no longer in a molten state.
