The present disclosure generally relates to the field of filtration. In particular, the present disclosure relates to filtration devices, systems and methods for high flowrates and low pressure differentials through porous bodies of metal fiber media.

The present invention provides a modification to the EBW process, which is referred to as a slope-out methodology, the results in the formation of a “slope-out portion” located generally in that region of the overall weldment located at the end of the ordinary EBW welding process for joining two components. The slope-out portion overlaps with the initial weld of the workpiece for a given distance or length along the weld and effectively eliminates the keyhole and provides a weldment that has minimal to no defects, particularly in the slope-out portion. The slope-out methodology begins by adjusting various parameters related to the electron beam to essentially decay the beam. In general, the focus position of the electron beam is moved from under-focused (focal position in the bulk of the material) to over-focused (focal position ahead of the workpiece surface) as the overlapping weld is made.

A weldment includes a first component, a second component, and a weld joint coupling the first and second components together. The weld joint forms a heat affected zone in the first component and creates residual tensile stress in the first component. The first and second components cooperate to define a pocket configured to position a highest magnitude of the residual tensile stress in the first component in a location that is outside of the heat affected zone of the first component.

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 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.

This disclosure relates to weldability of steel alloys that provide weld joints which retain hardness values in a heat affected zone adjacent to a fusion zone and which also have improved resistance to liquid metal embrittlement due to the presence of zinc coatings.

A method of manufacturing a fabricated object according to at least one embodiment includes a step of forming the fabricated object by laminating metal powder, the fabricated object including an opening portion that communicates with a hollow internal space, a step of mounting a plug in the opening portion, and a step of welding the plug mounted in the opening portion to the fabricated object.

A tubular member includes a tube body, a tube end, an exterior surface, an interior surface, a nominal wall thickness, a longitudinal axis, a welded seam, and a patch of material. The welded seam forms an arcuate portion of the interior surface, and the patch covers a portion of the interior surface that includes a portion of the welded seam, extending from the tube end to an axially spaced first location. The resulting interior surface from the tube end to the axially spaced first location has a uniform inside diameter.

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 method of repairing a compressor outlet housing includes the steps of obtaining a damaged compressor outlet housing having a radially outer volute, a radially inwardly extending finger extending to an axially extending ledge, a radially inwardly extending web extending radially inwardly from the ledge, and a radially inner bearing support defining a bore. The method identifies a damaged section within at least one of the bearing support, the web, and the ledge, and removes at least the bearing support and the web to leave a remaining part. The method then inserts an insert having at least a replacement bearing support and a replacement web into the remaining part after the removal step. The method then welds the insert to the remaining part to provide a repaired compressor housing. A method of replacing a compressor outlet housing and a replacement compressor outlet housing are also disclosed.
