Optimization of recycled slag-fresh flux mixture based upon weld bead quality for submerged arc welding of stainless steel

Submerged arc welding (SAW) has been performed using slag-fresh flux mixture on duplex stainless steel plates. Experiments were performed by recycled slag-fresh flux mixtures with iron powder; iron powder is mixed to maintain and enhance the weld strength. The effect of composition variation of slag...
