Abstract
In this work the effect of welding parameters on mechanical properties of S355JR structural mild Steel is studied using SMAW process and E6013 as filler electrode with Taguchi orthogonal array of L9. Welding parameters like, voltage, current and speed are used as independent variables and tensile strength, hardness of weld zone and hardness of HAZ are consider as the output response in this investigation. Signal to noise (S/N) ratio and ANOVA are performed to know the significant of the parameters and the optimal welding condition using MINITAB 18 software. The maximum mechanical properties of the welded sample are obtained for optimal welding conditions. The maximum tensile strength, hardness of weld zone and hardness of heat affected zone were obtained 494.47 Mpa, 269.77 and 255.06 respectively. From the investigation, the parameters of SMAW process like voltage, current and speed noted significant influence on the mechanical properties of the base metal.
