Abstract

This article attempts to predict the element transfer behaviour in the shielded metal arc welding process (SMAW). Suitable selections of coating compositions are critical and effective in improving the mechanical and metallurgical properties of weldments. In the present study 21, basic electrode coating compositions were decided by using Al2O3-SiO2-CaO SiO2-CaO-CaF2 and experimental phase diagrams. At constant welding parameters, twenty-one series of bead on plate experiments were performed by using developed SMAW fluxes. Using the mixture design, statistical approach different mathematical models was developed in terms of flux constituents. Regression equations in terms of individual, binary and ternary flux mixtures were developed. Results indicate that there were a predominant effect on weld metal-carbon, silicon, manganese, sulphur, phosphorous, molybdenum and chromium contents.
