  • Difference between ERW, DOM and Seamless Tube

    Mar 15, 2017 · ERW (Electric Resistance Welded) The nomenclature ERW refers to a specific type of welding process that involves both spot and seam welding. Seam welding is commonly used during the manufacturing of round, square and rectangular steel tubing. The steel strip is unwound from coils and side trimmed to control width and condition the edges for

  • 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.
