    摘要: Superalloy components, such as service-degraded turbine blades and vanes, are clad by laser beam welding. The welding/cladding path, including cladding application profile, is determined by prior, preferably real time, non-contact 3D dimensional scanning of the component and comparison of the acquired dimensional scan data with specification dimensional data for the component. A welding path for cladding the scanned component to conform its dimensions to the specification dimensional data is determined The laser welding apparatus, preferably in cooperation with a cladding filler material distribution apparatus, executes the welding path to apply the desired cladding profile. In some embodiments a post-weld non-contact 3D dimensional scan of the welded component is performed and the post-weld scan dimensional data are compared with the specification dimensional data. Preferably the welding path and/or cladding profile application are modified in a feedback loop with the pre- and/or post-welding 3D dimensional scanning.

A layer of powder (14) disposed over a superalloy substrate (12) is heated with an energy beam (16) to form a layer of superalloy cladding (10) and an overlying layer of slag (18). A filler material (44) of nickel, nickel-chromium or nickel-chromium-cobalt wire or strip is also added to the melt pool to combine with the melted powder via a submerged arc or electroslag heating process to give the superalloy cladding the composition of a desired superalloy material. The layer of powder includes a layer of powdered flux material (22) over a layer of powdered metal (20), or the flux and metal powders may be mixed together (36).

    摘要: Superalloy component castings, such as turbine blades and vanes, are fabricated or repaired by an electroslag or electrogas welding process that at least partially replicates the crystal structure of the original cast substrate in a cast-in-place substrate extension. The process re-melts the base substrate surface and grows it with new molten filler material. As the base substrate and the filler material solidify, the newly formed “re-cast” component has a directionally solidified uniaxial substrate extension portion that at least in part replicates the crystalline structure of the base substrate. The “re-cast” component can be fabricated with a unified single crystal structure, including the extension portion. In other applications, a substrate extension can replicate a directionally solidified uniaxial crystal structure of an original base substrate casting. Polycrystalline substrate base structures can be re-cast with a substrate extension that replicates base substrate crystals that are most parallel to the uniaxial casting direction.

    摘要: Superalloy components are joined by mating a recess formed in one component with a corresponding projection formed in another component along a contact surface. The components are compressed along the contact surface and resistance heat brazed to each other. Current is passed between the components at a selected flow rate and application time until brazing alloy melting occurs along the contact surface, and they are mutually affixed to each other. When repairing a damaged surface portion of a superalloy material component, the damaged portion is removed to form an excavated recess. A repair splice is formed, preferably of a same material with similar mechanical structural properties, having a mating projection with profile conforming to the corresponding recess profile. The splice and substrate are resistance heat brazed under compression pressure until brazing alloy melting occurs along the contact surface, so that they are mutually affixed.

    摘要: A method of applying a weld using a gas tungsten arc welding procedure. A filler element is provided to a welding location. The filler element includes a first material used during formation of a weld, and a second material that is capable of producing a slag upon melting thereof. A welding arc provides heat that melts portions of first and second components and the filler element proximate to the welding location to form a weld pool. The second material melts and forms a slag, which flows to an outer surface of the weld pool and shields the weld pool from exposure to reactive elements in the atmosphere. Upon cooling of the weld pool, the weld pool solidifies to form a weld between the first component and the second component.

    摘要: An assembly (10) that can be both joined and parted by temperature processing. A parting member (20) captured between two members of the assembly exhibits a state change as a function of temperature such that the two members can be joined with a meltable joining material (18) at a joining temperature, operated at an operating temperature lower than the joining temperature, and then separated at a parting temperature higher or lower than the operating and joining temperatures as a result of a parting force caused by the state change of the parting member. In one embodiment, the parting member has a coefficient of thermal expansion higher than a coefficient of thermal expansion of the assembly members such that differential thermal expansion causes the parting member to expand across the interface (16) between the members to generate the parting force.
