Electric Resistance Welded (ERW) pipe is manufactured by cold forming a flat steel strip into a rounded tube by passing it through a series of forming rollers to obtain a longitudinal seam. The two edges are then simultaneously heated with a high frequency current and squeezed together to produce a bond.

High frequency straight seam electric resistance welded steel pipe(erw steel pipe) is hot rolled coil after forming machine, the use of high frequency current skin effect and proximity effects, the tube edge heating and melting, squeeze roller under pressure welding to achieve production.
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.

May 12, 2015 · ERW (Electric Resistance Welded) The nomenclature ERW refers to a specific type of welding process that involves both spot and seam welding. Seam welding is commonly used during the manufacturing of round, square and rectangular steel tubing. The steel strip is unwound from coils and side trimmed to control width and condition the edges for welding.
