    摘要: Including a disk (12), a plurality of circumferentially spaced apart airfoils (16) extending radially outwardly from the disk (12), a plurality of shroud segments (18) being disposed circumferentially between the plurality of airfoils (16) and configured to attach to a corresponding airfoil of the plurality of airfoils (16) and a plurality of wear surfaces (22), where at least one wear surface of the plurality of wear surfaces (22) is configured and disposed to prevent excessive wear between the adjacent shroud segments (18). Each shroud segment of the plurality of shroud segments (18) may be attached to a corresponding airfoil (16) by weld connections (20) to permit clearance during translation friction welding of the airfoil (16) to the disk (12) hub are located to avoid high stress areas.

    摘要: A workpiece structure (40) having a hole (52) therein is repaired by preparing a stack (42) having a first confinement sheet (44), a first donor sheet (46), a workpiece structure (40) having a hole (52) therein, a plug (66) of a plug material in the hole (52), optionally a second donor sheet (64), and a second confinement sheet (47). The first confinement sheet (44), the first donor sheet (46), the second donor sheet (64), and the second confinement sheet (47) each overlie the hole (52). The first confinement sheet (44) and the second confinement sheet (47) each melt at a temperature greater than do the first donor sheet (46), the plug (66), and the second donor sheet (64). The stack (42) is locally heated at the hole (52) using an electrical current source to a temperature sufficiently high to locally melt the first donor sheet (46), the plug (66), the second donor sheet (64), and the workpiece structure (40). The stack (42) is thereafter cooled to solidify all melted material and form a weldment.

    摘要: A method for replacing a portion of a gas turbine engine rotor blade, the rotor blade having a contour defined by a blade first sidewall (70) and a blade second sidewall (70) includes cutting through the rotor blade such that a cut line (110) extends from a leading edge (74) of the blade to a trailing edge (76) of the blade, and between the first sidewall and the second sidewall, removing the portion of the rotor blade that is radially outward of the cut line, and coupling a replacement blade portion (120) to remaining blade portion (98) such that the newly formed rotor blade (150) is formed with a predetermined aerodynamic contour.
