摘要： The present method for machining a part includes wire electro-discharge machining the part to create a recast layer, and then removing a zinc content of the recast layer without substantially altering the remainder of the initial composition make-up of the recast layer. The final composition make-up of the recast layer is substantially identical to the initial composition make-up except for the removed zinc content.

摘要： A method of manufacturing a part, including providing a green body made of powder injection molding material and connected to a solid support member partially contained in the green body. The support member is engaged with a retaining fixture of a machine tool. While supporting the green body through the engagement between the support member and the retaining fixture, the green body is machined to obtain a machined green part. The machined green part is debound and sintered. A method of forming a powder injection molding part in a green state including machining a molded body using a machine tool while supporting the blank with a retaining fixture, and a machining blank having a green body and a solid support member including one locating feature of a pair of complementary locating features snuggly engageable with one another are also discussed.

摘要： A gas turbine engine case having a working fluid flow, includes inner and outer case portions defining an annular duct for directing the working fluid flow, and a plurality of struts positioned within the annular duct and extending between the inner and outer case portions. The struts are welded to the inner and outer case portions with a first weld along a peripheral line of the respective struts and with second weld, of fillet type, in selected locations for additionally connecting a portion of each strut to the respective inner and outer case portions.

摘要： A system and method for joining components together by projection welding and brazing are disclosed. In one embodiment, the method makes use of one or more weld projections extending from a first component and one or more spacer projections extending from either or both of the components. The one or more weld projections are taller than the one or more spacer projections by a meltdown distance that permits projection welding of the first and second components and permits the one or more spacer projections to define a brazing gap between the first and second components after projection welding.

摘要： The method can include inserting a first portion of a backing device into a fluid aperture of a first conduit component, inserting a second portion of the backing device into a fluid aperture of a second conduit component, and bringing the second conduit component adjacent the first component over the backing device, fusion welding the first conduit component to the second conduit over the backing device, and removing the backing device by circulating a fluid inside the welded conduit components. The backing device can be made of a soluble material.

摘要： A rotor for a gas turbine engine is described and includes a disc and a plurality of blades. The disc has opposite first and second end surfaces spaced apart by a peripheral surface circumferentially extending about the rotor, and a plurality of slots defined in the peripheral surface and each having a length extending between a first slot opening in the first end surface and a second slot opening in the second end surface. Each of the slots has a tapered shape with at least one dimension of a cross-sectional shape of the slot reducing along at least a portion of the length of the slot. The at least one dimension at the first slot opening is greater than the at least one dimension at the second slot opening. The blades having a complimentary root are received in the slots of the rotor.
