EFW steel pipe is the abbreviation of electric fusion welding.
One of submerged arc welding (SAW)-electric welding (EFW) is a process in which metal is heated by one or several consumable electrodes and a work piece to heat the metal, and the arc is used to make the metal and fill. The material is fully melted and does not require pressurization. The part of the filling metal is all from the electrode. Melt Gas Shielded Welding (GMAW)–A type of electrofusion welding (EFW) that is similar to submerged arc welding, but its protection comes from inert gases and works better.
