A fuel nozzle assembly for a gas turbine includes a plurality of circumferentially spaced vanes with holes for flowing fuel from plenums within the vanes through holes in the vane walls for premixing with air. To tune the nozzle assembly, the holes are resized by reforming the existing holes to a predetermined hole size, securing plugs into the holes, and forming holes through at least certain of the plugs to diameters less than the diameter of the existing holes.

A method for fabricating a rotor assembly for a turbine, the turbine including a central rotational axis is provided. The method includes forging a first rotor component from a first material, separately forging a second rotor component from a second material, and coupling the second rotor component to the first rotor component at a location radially inward of the first rotor component. The second rotor component is coupled to the first rotor component in at least one axial-circumferential plane that is at least one of substantially parallel and obliquely oriented with respect to the central rotational axis.

The pulsed partial pressure hydrogen cleaning of cobalt-based alloys in turbine components is achieved by disposing the component within a vacuum furnace and heating the component. Upon heating to about 1400 F. , a partial pressure hydrogen gas and a vacuum are repetitively cycled within the furnace by supplying in each cycle a fresh supply of hydrogen gas, followed by removal of reaction products between the hydrogen gas and surface contaminants and substantially all residual hydrogen gas from within the furnace. The repetitious cycling renders the surfaces clean, enabling refurbishment thereof by activated diffusion healing repair.

An apparatus and a method for repairing a component of a gas turbine engine is provided. The method includes locating a damaged area of the component, preparing a portion of the component that includes the damaged area leaving a remaining portion of the component, welding at least one layer of material to the remaining portion, using a cold metal transfer (CMT) process, and removing excess material from the component to a predetermined dimension.

A method for producing a component from two or more sub-components includes the steps of: producing each of the sub-components using an additive manufacturing process in which a resin, which is radiant-energy-curable, is partially cured using a selective application of radiant energy, wherein each sub-component includes a joint surface in which the resin is partially cured which is cured to a lesser degree than the remainder of the respective sub-component, so as to leave the joint surfaces in a condition suitable for bonding; assembling the sub-components with their respective joint surfaces in mutual contact; and performing a secondary cure of the partially-cured resin at the joint surfaces using an application of radiant energy, so as to further cure the partially-cured resin and bond the sub-components to each other, thereby forming the component.

An automated welding system includes a mounting platform configured to receive an object, a welding tool, an imaging device configured to acquire at least one image associated with the object, and a controller. The controller is configured to receive the at least one acquired image, analyze at least one pixel in the at least one acquired image, identify, based upon the analyzing, an area to be welded in the at least one acquired image, wherein the area to be welded includes a defect, and generate, based upon the identifying, control instructions for controlling at least one of the mounting platform and the welding tool to weld the area to be welded.

An automated welding system includes a mounting platform, a welding tool, an imaging device configured to acquire data associated with an object, and a controller. The controller is configured to receive the acquired data, determine an area to be welded in the acquired data, retrieve stored master model data associated with the object, and compare the acquired data to the stored master model data to identify a master model area in the acquired data. The controller is also configured to mask the master model area in the acquired data, such that the master model area is excluded from the area to be welded, and generate control instructions for controlling at least one of the mounting platform and the welding tool to weld the area to be welded.
