Process Parameters Optimization for Improving th Mechanical Properties of IS2062 MildsteelWeldments by GMAW

Mildsteel is the largely material for industrial and commercial applications. Gas Metal Arc Welding (GMAW) and Gas Tungstan Arc Welding (GTAW) process is the largely used metal joining process for thin gauge milsteel and stainless. This research focus on the on the effect of process welding parameters for acquring greater mechanical properties of weld plates. the Taguchi parametric optimization methodology and regression analysis is identified and used for Acquring the greater welding effectiveness and efficiency. The shielding gas, weld volrage& current is choosen as a process parameters for this research to Acquring the greater welding effectiveness and efficiency. At end of process, the mechanical properties like ultimate tensile strength, toughness and hardness of the weldment. After completion of the experimental work, the S/N ratio and mean S/N ratio were evaluated and the optimum values of each parameters was evaluated through the Taguchi method. Subsequently the significant co-efficient for each input factor of the mechanical properties was evaluated of by using the analysis of variance and prediction on the mechanical properties is evaluated by using regression analysi
