Submerged arc welding uses flux to shield the molten wire and working metal from contamination and to alter the chemical and mechanical properties of the weld. Subarc welding is said to permit ...

Large-diameter steel pipe are key players in the infrastructure and energy transport. Out of all the welded pipe types, Spiral Submerged Arc Welded ( ...

Submerged arc welding (SAW) is a specialised welding technique that reduces impurities from entering the weld pool by covering the entire arc with a pool of flux, resulting in cleaner welds.

Submerged Arc Welding (SAW) This uses a continuous solid wire, fed through a flux cover to the weld zone. The arc is generated below a layer of molten flux overlaid with unfused, solid grains of flux.
