What is the difference between HFW and ERW?

High-frequency welding (HFW) is a solid resistance heat energy.The use of high-frequency current welding resistance heat generated in the workpiece so that the workpiece is heated to melt the welding area or near the surface of the plastic state,then applied (or not applied) forging force and achieve a combination of metals.Welded Steel Pipes for Sales from leading Welded Steel According to different welding methods,it can be divided into arc welded pipe,high frequency or low frequency electric resistance welded pipe,gas welded pipe,furnace welded pipe,Bondi pipe,etc.Meanwhile,according to its steel characteristic and carbon content of steel,welded steel pipe also may be made by mild steel and high carbon steels.Welded Standard Line Pipe US Steel Tubular ProductsU.S.Steel Tubular Products high frequency electric weld (ERW) line pipe and standard electric resistance weld pipe products are smoothly finished and thin-walled.They are produced by continuously forming coiled hot rolled strip into a tube and welding the longitudinal seam using high-frequency electric resistance welding.
