EFW pipe vs ERW pipe. Electric Fusion Welding (EFW steel pipe) refers to an electron beam welding, the use of high-speed movement of the electron beam directed impact kinetic energy is converted to heat the workpiece so that the workpiece leaving the melt, the formation of the weld.. It is mainly used for welding dissimilar steel welding sheet or which high power density, (plate) What is ERW and HFW welding?What is ERW and HFW welding?ERW/EFW and HFW are welding methods in which pipe is welded without adding filler material.

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, the ERW steel pipe includes the HFW steel pipe.

High frequency welding (HFW) steel pipe is that ERW pipe produced with a welding current frequency equal to or greater than 70 kHZ. Through high-frequency current welding resistance, the heat generated in the contact objects, so the objected surface are heated to the plastic state, then with or without forging to achieve a combination of steels.(plate) Estimated Reading Time 7 minsDifference between ERW, HFW, SAW, EFW pipe & seamless (steel) Advantage of HFW pipe In the welding process, HFW steel pipes do not need to add filling meta. So it has fast welding speed and high efficiency in production. HFW pipe is widely used in the fields of oil and gas transportation, oil well pipeline, building structure, and various kinds of mechanical pipe.
EFW steel pipe (Electric Fusion Welding steel pipe) refers to an electron beam welding, the use of high-speed movement of the electron beam directed impact kinetic energy is converted to heat the workpiece so that the workpiece leaving the melt, the formation of the weld.
