Abstract:
A fixture for use in disposing a region of hardened material at a shroud face location for a rotor blade, the rotor blade being disposed about a spanwise axis, the rotor blade having a first end having a root section, an airfoil section which extends spanwisely, and a second end having a shroud extending laterally with respect to the airfoil, the shroud having a flow path surface, a shroud face location and a substrate for receiving the hardened material adjacent the shroud face location in molten form, which comprises:a base which engages the rotor blade;an assembly for urging a pad into engagement with the flow path surface of the shroud;a pad having a contour which adapts the pad to engage the flow path surface of the shroud, the surface being adapted to extend laterally beyond the hard face location of the shroud and beyond the shroud such that the pad in the engaged position blocks the flow of molten material to the flow path surface of the shroud.
