It includes contact welding and induction welding. Direct current welding is generally used for small caliber steel tubes. In general, HFW is one of ERW production methods, it adopts the high frequency welding process. So, ERW steel pipe includes HFW steel pipe.

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.erw hfw steel pipeerw steel pipeerw standard pipeerw tubing specificationshfw weldDifferences Between ERW and HFW Steel PipeERW steel pipe includes HFW steel pipe ERW is the general term for electric resistance welded steel pipe.
