Certain embodiments of the disclosed technology provide systems and methods for 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.

The present invention in some aspects is directed to small arms ammunition and programmed upset characteristics thereof imparted to them using high energy beams. More particularly, the invention relates to ammunition and methods of making ammunition having predetermined patterns of engraving and/or cutting or hardening and/or annealing imparted in the ammunition's forward portion using a programming laser or electron beam system adapted for treating projectiles to effect predetermined and consistent upset configurations.

Provided are a manufacturing system and a method for fabricating a component. The manufacturing system includes a wire delivery assembly arranged and disposed to deliver a wire feed to a fabrication assembly arrangement; the fabrication assembly arrangement includes a wire manipulation assembly, the wire manipulation assembly being arranged and disposed to convert the wire feed into a wire segment and position the wire segment on a workpiece positioner to form a workpiece stack; an energy beam source assembly arranged and disposed to direct one or more energy beams toward one or more aligned surfaces of adjacent wire segments within the workpiece stack, to weld the wire segments together. The method includes delivering a wire feed to a fabrication assembly; cutting and positioning a wire segment; and directing an energy beam toward one or more aligned surfaces of adjacent wire segments to weld the wire segments together.

A method for connecting two connection partners includes: moving a second connection partner towards a first connection partner and simultaneously heating a first section of the second connection partner to soften the first section; and placing the second connection partner on the first connection partner such that the softened first section of the second connection partner directly contacts the first connection partner.

Certain embodiments of the disclosure may include systems, methods, and apparatus for locating and drilling closed holes of a gas turbine component. According to an example embodiment, the method can include receiving position data associated with one or more holes in a gas turbine component; receiving predefined hole position data from manufacturing data associated with the gas turbine component; determining at least one missing hole, based at least in part on comparing the received position data to the predefined hole position data; and drilling at least one hole in the gas turbine component corresponding to the determined at least one missing hole.

A combustion pressure sensor having a tubular housing extending in an axial direction DX, a displacement member disposed within the housing, and a tubular connection member which elastically connects the displacement member to the housing. The combustion pressure sensor has a housing weld W1 that connects the housing and the connection member At least a circumferential portion of the housing weld is a bulge housing weld RW1 which bulges in a radial direction DR.

In an outer joint member of a constant velocity universal joint, a cup member and a shaft member are made of medium to high carbon steel and welded together. The cup member has a bottomed cylindrical shape that is opened at one end, and includes a cylindrical portion, a bottom portion, and a short shaft section of a solid shaft shape protruding from the bottom portion and having a joining end surface. The shaft member has a solid shaft shape and a joining end surface. The joining end surfaces of the cup and shaft members are brought into abutment against each other, and a high energy intensity beam is radiated from an outer side in a radial direction to form a welded portion. A structure of a molten metal at the welded portion is in a mixed phase of ferrite and granular cementite.

A porous aerostatic carrier includes a porous body made by additive manufacturing method and a sealing layer, the porous body comprises a first ventilating portion and a second ventilating portion, and a first porosity of the first ventilating portion is higher than a second porosity of the second ventilating portion. Because of additive manufacturing method, pore size and porosity of the first ventilating portion and the second ventilating portion are controllable to make flow pressure passing through the porous aerostatic carrier distributing evenly.

In some examples, a technique including positioning supports such that the supports are between a first metallic substrate and a second metallic substrate, wherein an undulating member is located between the first metallic substrate and the second metallic substrate, the undulating member defining a plurality of first peaks adjacent to a first surface of the first metallic substrate and a plurality of second peaks adjacent to a second surface of the second metallic substrate, wherein a first support of the supports is positioned such that the first support extends between a first peak of the plurality of first peaks and the second surface of the second metallic substrate; welding the first peak to the first surface of the first metallic substrate in an area of the first support; and removing the first support by at least one of a thermal removal process or a chemical removal process.
