Abstract: A weld spring clip used to tack weld two pipes together using a tungsten inert gas welder and a shield gas includes a reflector that can be inserted within a weld seam using a handle. The reflector, which is attached to an arm and a handle, is positioned beneath the desired weld site on the interior of the pipes. The handle biases the clip in place on the pipe at the seam, and a point on the end of the reflector assists in aligning the reflector at the seam. In position, the reflector reflects the shield gas toward the interior of the weld site. By reflecting the shield gas, oxidation along the interior surface of the weld site is prevented, and the need for a back gas is eliminated.

Abstract: In a method for overlap welding the inner surface of an elbow pipe, the elbow pipe is first divided axially into several pieces. These pieces are then stacked such that the inner arc of any piece is continuous with the outer arc of neighboring piece(s) to form an elbow piece stack. The inner surface of this stack may then be automatically overlap welded to a high uniformity of thickness using a relatively simple welding method. By fixing a short straight end tube to each end of the elbow piece stack it becomes possible using a relatively simple welding method to automatically overlap weld the entire surface area of the inner surface of the elbow piece stack continuously and to a high uniformity of thickness thus further improving productivity and quality of finish. The welded stack of elbow pieces is then dismantled and the elbow pipe is reassembled from the separate pieces.

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 welding apparatus and method is provided for automatically welding a stack of two or more metal tubes together. The tubes are stacked such that there is a pair of opposed longitudinal interfaces (or seams) between each tube in the stack. The welding apparatus broadly comprises: a stationary welding means for forming welds along the seams between each tube; a drive means for linearly advancing the stack of tubes relative to the welding means and for preventing separation of the tubes as the welds are being formed; and an alignment means for continuously and accurately keeping the stack of tubes in proper alignment as the drive means advances the tubes. The welding method broadly comprises: aligning the tubes in accurate stacked relation; holding the tubes together in stacked relation; advancing the tubes relative to a stationary welding means while maintaining the tubes in stacked relation; and welding the opposed longitudinal interfaces between each tube as the tubes are moved relative to the welding means.

Abstract: A metallic strip having at least one surface enhanced with a texture pattern is formed into a welded tube. A fin insert shapes the edges of the metallic strip prior to welding and minimizes the formation of a protruding weld bead. The longitudinally running edges of the metallic strip adjacent to the enhancement are angled so that the unenhanced portions of the strip edges contact during welding. By having the unenhanced portions contact, fluctuations in metal volume during welding are reduced. This reduces weld instability.
