    Abstract: Apparatus for end-to-end alignment of first and second sections of pipe for the welding together thereof including a frame assembly carrying independently expandable and retractable first and second axially spaced clamps for engagement and disengagement with the interior walls of said pipe sections. The frame assembly also carries a drive assembly by which the apparatus is propelled through said pipe sections and a brake assembly to slow or stop movement of the apparatus therein. Controls are connected to the clamps, the drive assembly and the brake assembly which are responsive to sensing of the end of the first pipe section by a sensor to deactivate the drive assembly, activate the brake assembly, arrest movement of the apparatus and, upon predetermined alignment, to activate the first clamp and finally the second clamp for engagement with the walls of the pipe sections.

    Abstract: A device for hindgas coverage in welding tube pieces (2,3) together comprises two sealing devices (5,6) connected by a rod (7). The sealing devices comprise a first web part (10) with sealing means (8) and a supply duct (11) for hindgas, and a second web part (9) with sealing means (8,25) and discharge ducts (19,20) for controlled outflow of gas to the surroundings. Some of the surfaces of each web part have a two-dimensional curvature (26) for forming the sealing means (8), e.g. rubber discs.

    Abstract: Apparatus is provided for profiling the end faces of pipes or tubes. The apparatus comprises a shaft one end of which is insertable into the open end of a pipe or tube to be profiled, collett means on said one end of the shaft, and cutting means rotatably mounted on said shaft for profiling the end face of the pipe or tube. The collett means comprises first and second screw threads of opposite hand on said one end of said shaft, a nut in threaded engagement with each of said screw threads, the nuts being movable in opposite directions along said screw threads when the shaft is rotated, and engaging means supported on said nuts and movable radially of said shaft into or out of engagement with the internal surface of the pipe or tube when the nuts are moved along said screw threads by rotation of said shaft. The screw threads are preferably coarse threads which with the differential effect of the opposed screw threads provides rapid engagement and disengagement of the collett means.

    Abstract: A method of arc welding is disclosed. Specifically, a method of pulsed direct current (DC) arc welding is disclosed wherein special pulses of positive direct current are used to weld together work pieces. The special DC pulses are capable of dissipating difficult to reduce oxides which may be present on the surfaces of the work pieces without using a flux. The method is especially useful for fluxless arc welding of aluminum, particularly thin wall aluminum tubing used in making heat exchangers for air conditioning systems.

    Abstract: Apparatus for rapid and automatic welding of joints which interconnect sections of pipe, and in particular oil or gas transmission pipe. The system includes at least one torch transport assembly which simultaneously moves a plural number of welding torches along a path parallel to the pipe joint being welded. The torch transport assembly includes track segments which surround circumferential portions of the pipe joint, with a welding torch carrier and multiple torches being independently movable along each track segment. The torch transport assembly is mounted on a support apparatus which is rigidly clamped to the pipe sections during welding, and which permits the torch transport assembly to be rapidly positioned in rough alignment with a pipe joint. The torch transport assembly and selected operating parameters of each welding torch are adjusted to accurately position each torch with respect to the pipe joint, and to repeatably provide programmed welding parameters resulting in a uniform pipe joint weld. The present system is disclosed in the context of hot-wire gas-tungsten arc welding torches, and in the operating environment of out-of-position joint welding.

    Abstract: Metal cans are welded by frictional treatment of the materials joined. The treatment is provided by a rapidly rotating smooth hard friction tool e.g. wheel contacting a surface of the metal above the join while the parts joined are held in pressure contact by independent pressure exerting means and/or by the wheel itself. In the formation of can side-seams the wheel and the can are relatively traversed and a longitudinal continuous side-seam is formed which in the case of metal to metal joints is metallurgically homogeneous and may be characterized in that no signs of melting of the base metal are visible at the welded interfaces.
