ABSTRACT

Arc welding is a type of welding process which uses an electric arc to create heat to melt and join metals. In these we have used mild steel grade 1018 as a base material of cross section 5mm, 8mm & 10mm and welded with different filler materials E6013, E9015, E308L to predict its strength and get comparisons of strength of the welded joint keeping welding current, voltage, heat input rate, welding speed and working temperature constant and left for air, water and sand cooling in normal room temperature for a fixed interval of time and finding the best suitable electrode for welding for a specific thickness of a mild steel grade1018. When the base material is welded, it is tested for its mechanical properties such as tensile strength test. This present experiment shows comparison of various mechanical properties when welded with different weld filler material with different thickness and varying voltages. To get the optimum result for the strength of the joint as today high quality with correct price is preferable for these TAGUCHI method is used to optimize the values of welding parameters in Minitab 2019 for getting best combination values for weld.
