Optimization of TIG Welding Process Parameters using Fractional Factorial Design of Experiment

TIG welding is preliminary welding process in heavy fabrication industry. There are differentOptimization Techniques, however experimental approach is fundamental approach, since itprovides mathematical model and hence opportunity for optimization using mathematicalmodel. This paper attempts to optimize the TIG welding process variables, using FractionalFactorial Design (FFD). It is very efficient and effective Optimization Technique, especiallywhen the experimental runs are time consuming and costlier from financial viewpoint (ProcessStability is important). It is found that the mathematical model is suitable in predicting theresponse. Optimum conditions of process variables are provided in the section “Optimization ofResponse
