SAW- Submerged Arc Welding (Long seam & Spiral Seam) ERW Steel Pipe Manufacturing Process 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. Residual stress prediction in submerged arc welded spiral Jan 01, 2012 · Abstract. Submerged arc welding (SAW) is generally the preferred method for joining the seam edges of large diameter spiral pipes. The quality control of the welded pipes usually consists of a hydrostatic test in which water is pumped into the pipe. High pressure hydrostatic tests can moderate tensile residual stress caused by the welding process.
The SAWH steel pipe is the spiral submerged arc welding steel pipe for short. It is made adopting sumberged arc welding technique and comes with a welding seam.
