Disclosed are a special tooling and method for electron beam welding of a cavity body and a beam tube of a superconducting niobium cavity. The special tooling includes a first clamping device for fixing a flange and a second clamping device for fixing a semi-cavity body, wherein the first clamping device and the second clamping device are fixedly connected. A pressing ring of the first clamping device is disposed around a beam tube of a superconducting niobium cavity and cooperates with a base plate to clamp and fix the flange. The second clamping device includes clamping arms evenly distributed along a circumference of the semi-cavity body, and each clamping arm includes a second pressing plate axially disposed along the beam tube and a pressing block that is disposed on an end portion of the second pressing plate and fixes an edge of the semi-cavity body.

A method of manufacturing an outer joint member of a constant velocity universal joint includes forming cup and shaft members of medium carbon steel, the cup member being manufactured by preparing a cup member having cylindrical and bottom portions being integrally formed, and a fitting hole formed in a thick portion of the bottom portion, the shaft member being manufactured by preparing a shaft member having a fitting outer surface formed at an end portion of the shaft member to be joined to the bottom portion of the cup member, and fitting the fitting hole of the cup member to the fitting outer surface of the shaft member. The method also includes welding the cup and shaft members from an inner side of the cup member to a fitted portion between the cup and shaft members.

Physical vapor deposition target assemblies and methods of manufacturing such target assemblies are disclosed. An exemplary target assembly comprises a flow pattern including a plurality of arcs and bends fluidly connected to an inlet end and an outlet end.

A vehicle spindle and a method of attaching the spindle to a portion of an axle half shaft housing. The spindle has an inner surface, an outer surface, one or more bearing journals on the outer surface of the spindle and a radially protruding portion circumferentially extending from at least a portion of the outer surface of an axially inboard end portion of the spindle. Prior to attaching the spindle to the axle half shaft housing, the one or more bearing journals are ground, a clocking angle for the radially protruding portion of the spindle is determined and the spindle is aligned to the determined clocking angle. Once the spindle is aligned to the determined clocking angle, the axially inboard end portion of the spindle is attached to an axially outboard end portion of the axle half shaft housing using one or more welds.

An airfoil including an airfoil body, a recessed portion of a first depth in a first side of the airfoil body, the recessed portion including a plurality of pockets of a second depth located within the recessed portion and ribs of the first depth located between the pockets, a cover configured to fit into the recessed portion such that an interior surface of the cover engages the ribs and an exterior surface of the cover is about flush with an exterior surface of the first side of the airfoil body, and a high energy beam weld configuration extending through the cover and into the ribs and positioned to attach the cover to the ribs.

The invention is an improved header and corresponding port associated with a transducer assembly. The header and port define mating threaded portions, thread stop portions, and a weld gap region. The thread stop portions are configured to mate and maintain a pre-loading tension between the threaded portions during and after applying a weld in the weld gap region. The weld gap region is configured to have a predetermined gap distance such that the weld seals the transducer without stress in the weld. The mating of the first and second thread stops are configured to maintain at least a portion of the pre-loading tension.

A subsea assembly comprising an electric subsea machine having an electric motor driving an operator, and a coolant circuit at least partially located in thermal contact with the electric motor, the coolant circuit including a cooling assembly located externally from the subsea machine, the cooling assembly comprising at least a heat transfer element, the subsea machine and the cooling assembly being supported by a common supporting frame; at least a part of the heat transfer element is integrated in the frame.

Disclosed is an improved method of manufacturing cooled accelerator grid with full penetration weld configuration. In a preferred form, the method includes the steps of: machining a plurality of stubs, a first and a second end of a plurality of inconel pipes; welding the stubs with the first end of the inconel pipes forming a water connector assembly; machining of a base plate; welding the base plate with the water connector assembly; machining the base plate welded with the water connector assembly, wherein machining further comprises milling of plurality of cooling channels across angled plane of the base plate welded with the water connector assembly; closing of plurality of cooling channels located on the base plate welded with the water connector assembly; and welding each of plurality of external hydraulic circuits with the second end of each of the plurality of inconel pipes.

A replacement compressor outlet housing includes a compressor outlet housing, having a volute and a radially inwardly extending finger extending from a radially inner end of the volute. The radially inwardly extending finger is welded to an insert. The insert has a bearing support defining a bore. The insert has a web connecting a ledge to the bearing support. The radially inwardly extending finger welded to the ledge.

A method is provided for manufacturing a segment of a drill string, such as a tubular tool, from a plurality of layers. The method includes arranging a plurality of layers based on a selected length of the segment. Each of the plurality of layers includes an aperture that is received over an alignment feature that restricts movement of the plurality of layers to two or fewer degrees of freedom. A joining process is performed to join the plurality of layers, which may include at least one replacement layer.
