Introduction to Welded Pipe Manufacturing - The Process Electric Resistance Welding (ERW) Process Submerged Arc Welding (Saw) Process Electric Flash Welding Process Lap Welding Process In Electric Resistance Welding (ERW) process, pipe is manufactured by cold-forming a flat sheet of steel into a cylindrical shape. Then current is passed between the two edges of the steel cylinder to heat the steel to a point at which the edges are forced together to form a bond without the use of welding filler material. Several Electric Resistance Welding (ERW) processes are available for pipe production. The two main types of ERW are 1.
