What is Submerged-arc Welding? - TWI

Submerged arc welding is ideally suited to the longitudinal and circumferential butt welds required for the manufacture of line pipe and pressure vessels. Welding is normally carried out in the flat (BS EN ISO 6947 PA) position because of the high fluidity of the weld pool and molten slag and the need to maintain a flux layer. Fillet joints may also be produced, welding in either the flat or horizontal-vertical (PB) positions. Further information. Submerged-arc Welding What does double submerged arc weld ( dsaw ) mean?Double Submerged Arc Weld (DSAW) Definition - What does Double Submerged Arc Weld (DSAW) mean? Double submerged arc welding is a process that involves two submerged arc welding passes. One pass of submerged arc welding takes place on one side of the material, and another pass takes place on the opposite side of the first pass.See all results for this questionWelding of pipes - SpesmetWelding during pipe production is mainly by submerged arc welding for larger diameter pipe and by electrical resistance welding (high frequency) for smaller diameter pipe. Mechanised gas metal arc welding systems remains the dominant welding technique for the fabrication of large diameter pipelines. Small diameter pipe welding is dominated by manual and mechanized (orbital) gas tungsten arc
