ERW pipe (also called ERW steel pipe) is the abbreviation Electric Resistance Welded Pipes. Electric resistance welding refers to a group of welding process (including spot and seam welding) that produce coalescence of faying surfaces where heat to form the weld is generated by the electrical resistance of material combined with the time and the force used to hold the materials together during welding. ERW steel pipes and tube are available in various qualities, wall thicknesses, and diameters of the finished pipes.
Applications
For low pressure fluid transmission, such as water pipelines, agriculture & irrigation (water mains, sewerage systems,industrial water lines, deep tube-wells & casing);
For machinery manufacturing, such as engineering purpose, fencing, scaffolding, line pipes etc.;
For Gas pipe lines (pipe lines for natural gas), LPG and other non-toxic gas.

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.
