ERW Pipe Manufacturing Process - Sunny Steel

ERW Pipe Manufacturing Process. Electric resistance welded (ERW) pipe is manufactured by cold-forming a sheet of steel into a cylindrical shape. Current is then passed between the two edges of the steel 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.
