  • APPARATUS AND METHOD FOR ORBITAL WELDING
    Publication number: 20210362260
    Abstract: An orbital welder for welding together two pipes to be welded. The welder includes a fall brake for preventing a freefall of the welder. The welder includes a spatter shield for preventing dust from entering the outer housing and fowling sensitive machine components. The welder includes a torch assembly with manual adjustments. The welder includes an automatic lead/lag adjustment and control of that adjustment during a welding operation to automatically transition from a first weld zone to a second weld zone.

  • Near-weld purge gas delivery system
    Patent number: 9969031
    Abstract: Apparatus, systems, processes, control systems, means and methods for near-weld gas purging and welding. A focused circumferential near-weld purge gas delivery system for pipeline welding. A near-weld purge rig which has a near-weld purge gas channel and which achieves a low oxygen concentration proximate to a pipe gap for welding. The gas used for purging is also directed against an interior surface of the pipe to be welded. The directed gas cools the pipe to a desired temperature.
