Jan 22, 2013 · TIG welding is traditionally used for welding stainless steel tube and pipe, and remains the optimal solution for extremely high purity applications on tube or pipe at or below 6-inch diameter and schedule 10 wall thickness. The preferred method for high purity food-grade stainless steel is an autogenous TIG square butt weld. Welding of Large Diameter Pipelines:Design, Processes Weld After Backfill is a sequence used to improve overall installation rate for steel pipe. Pipe is laid and welded outside (if required). Joint coating is applied, usually a shrink sleeve or mortar diaper. Pipe is backfilled. The inside weld is made later.
