Abstract: Submerged Arc Welding (SAW) can be employed for an extremely wide range of work piece. The method is suitable for butt welding and fillet welding of such applications as structural members in ship, manufacture of pressure vessels, bridge beams, massive water pipes, thin sheet shells and so on. Rotatable designs based on statistical experiments for mixtures have been developed to predict the combined effect of flux mixture and welding parameters on submerged arc weld metal chemical composition and mechanical properties. Bead-on-plate weld deposits on low carbon steel plates were made at different flux composition and welding parameter combinations. The results show that flux mixture related variables based on individual flux ingredients and welding parameters have individual as well as interaction effects on responses, viz. weld metal chemical composition and mechanical properties. In general, two factor interaction effects are higher than the individual effect of mixture related variables. Amongst welding parameters, polarity is found to be important for all responses under study.
