摘要：Tungsten inert gas welding process is amulti-input and output process in which the resultant jointstrength is governed by both individual and combinationof process parameters. The identification of suitablecombination parameter is crucial to get desired quality ofwelded joint and hence, there is need for optimization oftungsten inert gas welding process to achieve a soundweldment. The present work is based on the TIG weldingprocess parameters on welding of AZ61 magnesium alloy.The design of experiment is done by Response surfacemethodology techniques to find the desired weldingconditions for joining similar AZ61 magnesium alloymaterial. Analysis of variance methods were applied tounderstand the TIG welding process parameter. Theconsidered parameters are welding current, welding speed,arc voltage, electrode stick out, while the desired outputresponses are tensile strength and percentage elongationof the welding joints. From the results of the experiments,mathematical models have been developed to study theeffect of process parameters on tensile strength andpercentage elongation. Optimization is done to findoptimum welding conditions to maximize tensile strengthand percentage elongation of welded specimen.
