  • Submerged Arc Welding (saw) : Maine Welding Company

    The flux forms a glass-like slag that is lighter in weight than the deposited weld metal and floats on the surface as a protective cover. The weld is submerged under this layer of flux and slag, hence the name submerged arc welding. The flux and slag normally cover the arc so that it is not visible. The unmelted portion of the flux can be reused. It is not possible to stop the generation of slag because it is a by-product of the process but slag can be reused as a flux in the same submerged arc welding process. Wastivity can be decreased by recycling the slag thus resulting in higher productivity. Furthermore, the slag can be processed according to one's requirements and applications. 2.

    Stopping, reducing or recycling the waste generated in a process is an effective method to improve its productivity. Flux used in submerged arc welding/cladding gets converted to slag, which is a waste and is needed to be disposed off safely. The quantity of slag produced during the process is very high. Minimizing time spent to remove light scale/rust before welding and chipping slag between weld passes is also ideal. Reconsidering the existing weld joint, equipment setup, and filler metal and flux selection can help to reduce welding cycle time and eliminate arc-off activities to further enhance the benefits of the SAW process.
