The difference between ERW and EFW DMH United Steel

ERW is the first letter of resistance welding Electric resistance welding abbreviation ERW pipe and submerged arc welding pipe welding methods are significantly different, the use of unfilled metal pressure welding, the weld is not filled with other components, by high frequency current The skin effect and the proximity effect, so that the instant plate edge heated to the welding temperature

Electric resistance welding at a glance The FABRICATOR

Jun 13, 2002 · Several electric resistance welding (ERW) processes are available for tube and pipe production. While each process has different characteristics, all ERW processes have one thing in common–all of them produce a forged weld. A forged weld is created by applying a combination of heat and pressure, or forging force, to the weld zone.

Electric resistance welding Wikipedia

Electric resistance welding (ERW) refers to a group of welding processes such as 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. Some factors influencing heat or welding temperatures are the proportions

What is the difference between HFW and ERW?

High frequency welding (HFW)   is a solid resistance heat energy. The use of high frequency current welding resistance heat generated in the workpiece so that the workpiece is heated to melt the welding area or near the surface of the plastic state, then applied (or not applied) forging force and achieve a combination of metals.

Electric resistance welded tubing :ArcelorMittal USA

In ERW tubing, slit to width flat steel strip passes through a series of tooling rolls that progressively cold form it into a tubular shape. Using high frequency induction, heat is generated by the natural resistance of the steel to an electric current which is confined to the narrow strip edges in the weld vee.

Differences between ERW Steel Pipe and HFW Steel Pipe

ERW steel pipe is manufactured through low or high frequency resistances Electric Resistance. Welding seam is in longitudinal. During the ERW pipe welding processes, the electric current will make the heat when flow through the contact surface of the welding area. It will heat the 2 edges of the steel to a point that the edges can form a bond.
