    Abstract: A lightweight, portable clamping device assists in holding and reforming pipes in piping systems. The clamping device comprises a pair of semicircular clamp halves which are placed on the abutting ends of out-of-round pipe. The clamp halves are drawn together by tightening bolts on either side to align and reform the ends of abutting pipes. The clamping device can also be used to shape and hold the end of a single piece of pipe. A plurality of access ports around the perimeter of the device allow a welder to tack weld the ends of abutting pipes prior to welding.

    Abstract: A process for buttwelding metal workpieces having bevelled joint preparations using an automatic GTAW welder using filler wire includes preparing the bevelled workpiece with bevelled joint areas having minimal land thickness at the root extremities; placing the prepared workpiece joint sections together with an open gap between their adjacent root extremities, the gap having a minimum dimension that avoids harmful compression stress between the workpieces due to weld shrinkage and a maximum dimension that avoids filler wire penetration of the gap; fusion welding the open root area of the adjacent workpieces with a root pass weld using an automatic GTAW welder supplied with filler wire and a shield gas including 1 to 10% hydrogen and the balance inert gas; and then promptly overlaying the root pass weld with at least one additional filler weld pass using an automatic GTAW supplied with filler wire and hydrogen-free shield gas.

    Abstract: A dual bias weld is an improved weld for joining strips to be formed into coiled tubing. Tubing is formed from a first strip and a second strip, the first and second strips being of the same width. A planar end surface is formed on an end of the first strip, the plane of the planar end surface being defined by a line lying along a top surface of the first strip at an acute angle with respect to the longitudinal direction of the first strip and a line lying along an edge surface of the first strip at an acute angle with respect to the longitudinal of the first strip. Similarly, a planar end surface is formed on an end of the second strip, the plane of the planar end surface being defined by a line lying along a top surface of the second strip at an acute angle with respect to the longitudinal direction of the second strip and a line lying along an edge surface of the second strip at an acute angle with respect to the longitudinal direction of the second strip. A composite strip is formed by welding the planar end surface of the first strip to the planar end surface of the second strip to form a dual bias weld. Excess weldment is then removed from top, bottom and edge surfaces of the composite strip such that the width of the weld is identical to the width of the first and second strips. Coiled metal tubing is then formed from the composite strip.

    Abstract: An apparatus and method for resistance welding tubular parts. The apparatus includes a weld gun having electrodes with arcuate contact faces engaging the parts. The electrodes are displaceable relative to each other. The contact faces are designed to distribute the force applied to the parts to prevent deformation and to hold the parts together steadily in order to minimize the amount of undesired electrode displacement caused by these effects. A test computer monitors the amount of electrode displacement occurring as a result of penetration of the parts into each other during welding. When the displacement between the electrodes falls within a predetermined displacement range, which is indicative of a proper weld between the parts, the computer cooperates with a weld controller to terminate the welding power, thereby inhibiting any substantial further penetration of the parts. The apparatus and method is suitable for tube-to-tube and wire-to-tube applications commonly performed in the manufacture of automobile seats.

    Abstract: A fixture for aligning clamping pipes end to end to enable joining the pipes by welding includes a collar circumscribing one of the pipes and circumferentially spaced arms extending outwardly from the collar and then coaxially with the pipes. Pipe damps are supported by each of the arms at approximately 120 degrees intervals about the pipe. The stems of the clamps are supported by the arms such that proper orientation of the clamping shoes and guide members is assured. Furthermore, an extension of the stem which projects between the pipes and carries an inner guide member for engagement with the inner circumferential surface of the pipe has a differential thickness such that the pipes are initially separated by a predetermined thickness by engagement of the pipes with the necked portion of the extension for tack welding. After tack welding is complete, the stems are rotated 90 degrees, thereby bringing a narrower dimension of the necked portion into registry with the gap between the pipes, permitting withdrawal of the stems.
