Abstract:
A method is provided for reworking a component. The method includes at least partially filling a cavity in a non-fusion weldable base alloy with a multiple of layers of a multiple of laser powder deposition spots formed of a filler alloy. Each of the multiple of laser powder deposition spots at least partially overlaps at least one of another of the multiple of laser powder deposition spots. The filler alloy may be different than the non-fusion weldable base alloy.
Abstract:
The present disclosure relates generally to a system and method for applying a metallic coating. A first metallic coating may be applied to a portion of a total surface of a part and a second metallic coating may be applied to substantially the total surface. The metallic coating may be applied to a vane cluster for use in a turbomachine.
Abstract:
A method of reworking an aerospace component includes removing a casting defect from a component manufactured of a non-fusion weldable base alloy to form a cavity. The cavity is then at least partially filled with a multiple of layers of discrete laser powder deposition spots of a filler alloy. A cast component for a gas turbine engine includes a cast component non-fusion weldable base alloy with a cavity filled with a multiple of layers of laser powder deposition spots of a filler alloy. The filler alloy may be different than the non-fusion weldable base alloy. A layer of non-fusion weldable base alloy is at least partially within the cavity and over the filler alloy.
Abstract:
A method of reworking or repairing a component includes removing a casting defect from a component manufactured of a non-fusion weldable base alloy to form a cavity that results in a through hole; sealing the through hole with a backing; and at least partially filling the cavity with a multiple of layers of a multiple of laser powder deposition spots, each of the multiple of laser powder deposition spots formed of a filler alloy, a first layer of the multiple of layers includes a perimeter of the multiple of laser powder deposition spots that overlap a wall of the cavity and the backing.
Abstract:
A weld clad layer having a substantially equiaxed grain microstructure may be formed by forming a repair area in a substrate, depositing a first layer of laser deposition spots in the repair area, and depositing a second layer of laser deposition spots over the first layer of laser deposition spots. The first layer of laser deposition spots may comprise a first laser deposition spot and a second laser deposition spot adjacent to the first laser deposition spot. The first laser deposition spot may solidify prior to deposition of the second laser deposition spot. The first layer of laser deposition spots may comprise titanium or titanium alloy.
Abstract:
A method is provided that involves a component including a first fastener aperture that extends through the component. During the method, the component is machined to enlarge the first fastener aperture to provide an enlarged aperture. The component is friction plug welded to plug the enlarged aperture with friction plug welded material. A second fastener aperture is machined in the friction plug welded material, where the second fastener aperture extends through the component.

Abstract:
A method of repairing defects in a casting formed from non-weldable or difficult-to-weld alloys is disclosed. The method includes removing the defect from the casting thereby forming a cavity in the casting, placing a filler material in the cavity and fusion welding the filler material in the cavity. The fusion welding produces surface cracks on the casting and sub-surface cracks in the casting. The method then includes brazing at least some of the surface cracks on the casting and processing the casting with a hot isostatic pressure (HIP) process to close at least some of the sub-surface cracks in the casting.
