ASME ANSI B16.5 BE ends are the most common type of finish ( joints realized by welding pipes with but weld fittings and flanges). It is the metal pipe end that needs to bevelled. The pipe end beveling or pipe end finishing is a way to get an accurate weld surface as a base before the welding started.Pipe Manufacturing Process / Methods for Seamless & Welded In the ERW / EFW / HFW pipe process, the first plate is formed in a cylindrical shape and the longitudinal edges of the cylinder formed are welded by flash-welding, low-frequency resistance-welding, high-frequency induction welding, or high-frequency resistance welding. erw-pipe-manufacturing process SAW Pipe Manufacturing Process. In the SAW welding process, external filler metal (wire Petrosadid: Electric Resistance/ Fusion Welded (ERW and EFW)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.
