A design for tank fabricating equipment and system comprises a frame supporting opposing arms for supporting one or more tank shells. The opposing arms pivotally engage opposing sides of the tank shells to force them into a circular cross-sectional shape. The arms are provided with rollers for aligning the tank shell with adjacent components during fabrication. In some embodiments, the rollers are provided with a circumferential channel to accommodate welding seams and to ensure alignment of butt joints.

A stainless-steel welding wire for use in manufacture of an LNG tank is described. From the welding wire, it is possible to obtain a weld metal having excellent tensile strength and impact value because the contents of Ni, Mn, Mo, and Cr in the welding wire are adjusted. The welding wire can be applied to welding of all of 9% nickel steel, high manganese steel, and stainless-steel materials by adjusting the content relationship of Ni, Mn, Mo, and Cr, and has the effect of obtaining a weld metal with excellent ultra-low temperature toughness in the weld zone.

A jacketed vessel for temperature control of contents within the vessel is provided. The vessel has a shell and an external jacket through which heating or cooling fluid is circulated. The jacket is formed by a length of conduit arranged in a spiral orientation around the vessel shell. The conduit has a center portion having a concave inner surface and has opposing side portions having convex inner surfaces. Edge sections of each side portion are welded to the exterior surface of the shell to form the jacket. Edge sections of adjacent arcs of conduit may be simultaneously welded to the shell in a single weld pass. The shape of the conduit provides improved heat transfer and pressure drop characteristics, as well as improvements in the vessel manufacturing process.

An energy storage device is equipped with a container having a container body and a lid body, which closes an opening of the container body. An elongated welded part which is a welded portion between the container body and the lid body, is formed on the container. The welded part has a first welded part and a second welded part arranged in a row in a lengthwise direction of the welded part, wherein a width of the second welded part in a widthwise direction of the welded part is set larger than a width of the first welded part in the widthwise direction. A gas release vent is disposed on the lid body, wherein the second welded part is disposed on a lateral side of the gas release vent, and a length of the second welded part in the lengthwise direction is set larger than a length of the gas release vent in the lengthwise direction.

A spot welding jig is provided. The spot welding jig presses electrode leads of battery cells to be closely adhered onto a bus bar when spot welding is performed to the electrode leads interposed on the bus bar along a width direction of the electrode leads. The spot welding jig includes a passing portion through which a welding laser passes, and a predetermined number of barriers configured to vertically partition an inner space of the passing portion.

A pressure vessel includes: (a) a cylindrical sidewall having a wall thickness, an inside surface, an outside surface, and the cylindrical sidewall extending between a first end and a second end, wherein one of the first end or the second end includes a sidewall edge that forms part of an outwardly opening weld groove; (b) an end cap constructed to engage the cylindrical sidewall edge, the end cap comprising an end cap edge corresponding to the sidewall edge and that, when combined with the sidewall edge, forms the outwardly opening weld groove; (c) a cylindrically extending backer bar located in support of the outwardly opening weld groove formed by the sidewall edge and the end cap edge; and (d) a weld joint formed in the outwardly opening weld groove and holding the cylindrical sidewall to the end cap. A method for welding a pressure vessel sidewall and end cap together is provided.

A method for making a container for retaining anesthetic agent. The method includes creating two or more parts each having a mating surface, where the container is formed when the mating surfaces of the two or more parts are coupled together, and where a first part of the two or more parts is formed of a material having pores defined within the mating surface thereof. The method further includes processing the mating surface of the first part via friction stir welding to reduce the pores defined therein. The method further includes coupling the two or more parts together such that the mating surfaces contact to create the container configured to retain the anesthetic agent therein.

A robotic welding device employing a flexible guide rail comprises: a control box (2) pre-storing various welding processes and generating a welding parameter; a wire feed mechanism (7) feeding a welding wire to a welding gun (4); a flexible guide rail (8) attached to a welding component with the flexibility thereof; a welding robot comprising a robot body (3) and a welding gun (4), the robot body (3) being movably disposed on the flexible guide rail (8) along the same, and the welding gun (4) being disposed on the robot body (3) and controlled by the same to weld the welding component; a demonstrator (6) signally connected with the welding robot and the control box (2), controlling, a traveling path and an operation position of the welding robot, and adjusting oscillation and welding operations of the welding gun (4) according to an instruction of the control box (2); a remote control terminal (11) signally connected with the control box (2) so as to remotely monitor and configure the welding parameter, and signally connected with a data acquisition device of the welding robot so as to remotely monitor and configure the welding parameter during a welding process; and a welding power supply (1). The device enables automatic welding of a component with straight shape or arc shape.

A method of forming a canister by means of a mechanical bonding of respective layers of a first metal material (tantalum) and a second metal material (niobium) to form a sheet stock, thereby forming the sheet stock into a canister form, wherein the first metal material comprises tantalum and the second metal material comprises at least one of niobium, molybdenum, or steel. The completed canister comprises a first metal material comprising tantalum, and a second metal material mechanically bonded to the first metal material by subjecting the first and second metal materials to at least 1,000,000 psi, to thereby form a canister having an inner diameter of 13-19 millimeters (mm), the second metal material comprising at least one of niobium, molybdenum, or steel.
