SAW, Slag-Mix.Abstract
Slag formed during SAW process has been collected and processed for using further in subsequent runs of Submerged Arc Welding of mild steel material. The mixture of fused flux (slag) and fresh flux has been used as an alternative of fresh flux. The percentage (by volume) of slag in the mixture of fused flux and fresh flux has been termed as slag-mix%. The aim is to observe whether any noticeable adverse effect occurs on weld microstructure while consuming increasing percentage of slag-mix in SAW process. The present investigation leads to the idea that reconsumption of slag in SAW process does not impose any alarming adverse effect on parameters of the desired weld quality in terms of weld micro structure.
