The research on controlling metal transfer modes in the SAW process is essential to have high-quality welding with minimum cost. As a part of the study, on the effects of process parameters on weld bead geometry in Submerged Arc Welding (SAW), a technique that has proved very useful in reducing to a minimum number of experiments required is a branch of applied mathematics known as factorial design technique or fractional factorial design technique. Weld bead size and shape are important considerations for design and manufacturing engineers in the fabrication industry. This is done to specify and establish the interrelation between the mechanical properties and the various weld parameters as well as it also investigates the most ideal combination of the various parameters which gives good weld quality, high strength, and durability. In this study manual Metal Inert Gas (MIG) welding setup modified into a semi-automatic SAW facility, has been used. For this investigation, a statistical technique, response surface methodology (RSM) with Minitab 2017 has been used for the analysis of the direct and interaction effects of the process. Weld beads were deposited with bead-on-plate techniques using copper-coated mild steel wire and agglomerated flux for shielding on mild steel plates.
