Abstract
In this work focus is given for obtaining reliable welded joint while joining dissimilar metals in Manual (Shielded) metal arc welding process by optimizing the input parameters. Stainless steel 304 and mild steel 1018 were welded by Shielded metal arc welding method which is commonly used in fabrication industries. 309L grade electrode is used for joining the dissimilar materials. In this study the independently controllable process parameters affecting the weld strength, Metal deposition rate and Bead height are welding current, welding speed, root gap, electrode angle. The experimental runs were planned by using central composite system of Response surface Methodology. On analyzing the process parameters by using RSM, it is found that Welding strength 394.5 N/mm2, Metal deposition rate 12.8 gms and Bead height 5.6 mm were obtained with setting of process parameter as Welding current 101 A, Welding speed 7 mm/s, Electrode angle 600 and root gap 1.25 mm. Same results were cross validated by conducting the experiments with optimized process parameters.
