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 Spiral welding?What is Spiral welding?In Spiral Submerged Arc Welding (SSAW) Process, also known as HSAW pipe, welding line shape like a helix. It is using the same welding technology of Submerged Arc Welding with LSAW pipe. Only major difference being SSAW pipe is spiral welded whereas the LSAW is longitudinally welded.Introduction to Welded Pipe Manufacturing - The Process Piping What is double submerged arc welded pipe?What is double submerged arc welded pipe?The manufacturing of Double Submerged Arc Welded Pipe involves first forming steel plates into cylindrical shapes.
