Longitudinal Submerged Arc Welding Pipe Welded Description

Longitudinal Submerged Arc Welding (LSAW) Processes Longitudinal Submerged Arc Welding Pipe Welded

Longitudinal submerged arc welded (LSAW) pipes manufacture process is bending and welding wide steel plates to pipes from leveled hot rolled coils by both the JCOE and UOE (the forming process in which the plate like the letter "J", "C", "O" or "U" shape, then expansion) forming processes. What is a submerged Weld?What is a submerged Weld?The weld is submerged under this layer of flux and slag, hence the name submerged arc welding. The flux and slag normally cover the arc so that it is not visible. The unmelted portion of the flux can be reused. The electrode is fed into the arc automatically from a coil. The arc is maintained automatically. Travel can be manual or by machine.Submerged Arc Welding (SAW) - Weld Guru What is longitudinal welding?What is longitudinal welding?Longitudinal Submerged Arc Welding is a specific welding technique used in pipe production where the finished product requires a particularly high wall thickness due to high internal or external pressures.Longitudinal Submerged Arc Welding (LSAW) Processes Longitudinal Submerged Arc Welding Pipe Welded
