Abstract:

The Objectives of this research is to study the effect of mixture of reused and new flux on chemical composition in weld metal of Submerged Arc Welding process (SAW). Slag generated during submerged arc welding has been recycled by mixing varying percentages of crushed slag with fresh flux to use in subsequent runs. Slag generated during submerged arc welding is normally thrown away as a waste. This poses the problem of storage, disposal, and environmental pollution and needs landfill space apart from exhaust of non-renewable resources. Reusing of slag will not only solve these problems but also be economical. In the present work an attempt has been made to use the submerged arc welding slag as flux in the same submerged arc welding process.
