Abstract: An apparatus for providing inert gas to a desired location for a welding operation is provided. The apparatus includes a gas feed line and structure for mounting the feed line to extend in a first direction in a pipe. A gas locator tube communicates with the gas feed line to direct inert gas from the gas feed line in a second direction, different from the first direction, towards a pipe joint to be welded. The locator tube is capable of continually directing inert gas in the second direction as the pipe is rotated during a welding operation.

Abstract: An expandable tool for holding and aligning pipes to be welded together is disclosed. The tool includes an annual array of radially movable gripping elements for engagement with the interior wall of the pipes to be welded. A wedge is mounted for axial movement relative to the gripping elements to effect selective radial outward movement of the gripping elements to align and hold the pipes for welding. The gripping elements are provided with passageways for delivery gas to preselected zones between the gripping elements and the interior wall surfaces of the pipes in the regions to be welded.

Abstract: A method for manufacturing a welded metal container by first arc welding a branch pipe to a trunk pipe. The arc welding of the pipes together causes both of the pipes to be thermally deformed. The end surfaces of the pipes are then cut by a laser cutting or mechanical cutting process so that the ends of the trunk pipe are in parallel and perpendicular to the end of the branch pipe. Subsequently flanges are laser welded to the ends of the pipes without further thermally deforming the pipes. The metal container made by this process can be used as a sheath for a gas insulated switch gear.

Abstract: A resistance welding method for a fuel rod is presented in which the gas seal opening is closed with a sealing material of the same composition as the end plug material. The method enable to perform welding stably in a pressurized welding chamber, and the process is amenable to automation. The sealing material body is made of a wire, and is pressed against the conical shaped opening provided on the end plug. The welding method avoids contaminating the weld with undesirable impurities from the electrode material, and the welding operations is designed so that there is no need to reshape the end of the electrode or adjust the gap between the sealing material and the seal opening.
