Spirally welded steel pipes - ArcelorMittal PilingThe welding of the spirally welded pipes is based on the Double-Sided Submerged Arc Welding (DSAW) process. The principle Arc welding works by using electric current to produce an electric arc in a gas environment. The arc's heat brings the metal to fusion point. A key question is how to increase both the concentration and energy intensity of
Jan 09, 1993 · In Duplex Stainless Steels, 1997. 9.4.2 Submerged arc welding. Submerged arc welding (SAW) is an attractive process for larger pipes, vessels and heavier wall thickness components in general. Practical experience is generally good, although nitrogen-induced porosity and transverse and longitudinal cracks have been observed. 7 These cracks are not always easy to observe on X-ray
The difference between ERW steel pipe and spiral steel Jun 03, 2018 · The ERW welded pipe has a simple production process, high production efficiency, low cost, and rapid development. Spiral steel pipe is a coiled steel pipe made from strip coils as the raw material, which is often warm extruded and welded by an automatic double wire double-sided submerged arc welding process.

More requirements on spiral steel pipe specifications. B. Adopting advanced double-sided submerged arc welding technology, welding can be realized in the best position, and it is not easy to have defects such as wrong edge, welding deviation, and incomplete penetration, and it is easy to control the welding
What Is Double Submerged Arc Weld (DSAW) - steel pipe Double Submerged Arc Weld (DSAW) Submerged Arc Welded (SAW) pipe derives its name from the process wherein the welding arc is submerged in flux while the welding takes place. The flux protects the steel in the weld area from any impurities in the air when heated to welding temperatures.
What is DSAW PIPE? - DMH United SteelDouble Submerged Arc Welded steel pipe is available in straight and spiral welded formats and used in a variety of applications. The submerged welding process protects the steel from contamination of impurities in the air. Both inside and outside welds are performed. DSAW pipe can be specified in very large diameter and to exact inside or
