Difference of ERW and EFW - Articles Factory

ERW That first letter of the acronym ERW Electric resistance welding ERW pipe and submerged arc welding pipe significantly different, with the pressure welding without filler metal, weld not filled with other ingredients, by high-frequency current skin effect and proximity effect, instantly heating the plate edge to welding temperature by squeezing rollers squeeze forging formed weld tissue. Differences between ERW Steel Pipe and HFW Steel PipeHigh 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.
