Saw-flux

SAW Flux (Submerged Arc Welding Flux) is a granular material used in the Submerged Arc Welding process to protect the weld area from atmospheric contamination. It forms a protective layer over the molten weld pool, ensuring clean, strong, and high quality weld joints. SAW flux plays a vital role in improving weld strength, arc stability, and overall welding performance.

During the welding process, the flux melts and forms slag over the weld bead, which prevents oxidation and contamination. It also helps in refining the weld metal, controlling bead shape, reducing spatter, and enhancing mechanical properties. After cooling, the slag can be easily removed.

SAW flux is widely used in heavy fabrication, shipbuilding, pressure vessels, pipelines, structural steel manufacturing, and industrial construction projects where deep penetration and high deposition rates are required.
