The submerged arc welding process is suitable for the requirements of heavy industrial applications such as pipelines, pressure vessels and tanks, locomotive manufacturing, heavy construction, and excavation. It is suitable for industries that require high productivity, especially those involving very thick materials, and can be buried from There are many benefits obtained in the arc welding Submerged arc welding pipe, SAW pipes, SAW pipe 439 stainless welded steel pipe Submerged arc weldingSubmerged arc welding pipe, SAW pipes. SAW is normally operated in the automatic or mechanized mode, however, semi-automatic (hand-held) SAW guns with pressurized or gravity flux feed delivery are available. Submerged arc welding (SAW) is a common arc welding process. The process is normally limited to the flat or horizontal-fillet welding positions (although horizontal groove position welds have
