摘要 |
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. |
