      What is a HFW steel pipe? - ugsteelmill

      Dec 04, 2018 · The high frequency welding (HFW) is mainly used in ordinary or thin wall steel pipe. 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. What is high frequency (HF) induction welding? - TWIHigh frequency induction welding is used to make pipe or tube from strip which is fed into rolls which form the strip into a cylindrical shape. The faying edges are brought together between squeeze rolls to produce a V at the point of welding, with an included angle of typically 2-5° for steel. A high frequency coil introduces current into the tube ahead of the squeeze rolls.
