Abstract:
Optimization of Manufacturing Processes presents a significant challenge to modern day
manufacturing industries as well as an opportunity to realize significant improvement in
quality, cost and consistency of products. Gas Tungsten Arc Welding is one such
manufacturing process which finds application in a wide array of industries but still
optimized welding parameters are hard to be determined.
This research investigation presents a review of various optimization techniques that have
been developed over the years and applied by researchers for the optimization of different
manufacturing processes. The review has been concluded with the selection of Taguchi
optimization technique which is often the best suited method for GTAW process
optimization in industrial environment. Experiments have been designed and conducted
based on Taguchi optimization techniques, keeping in view the critical process
parameters and required quality attributes. Results have been analyzed using ANOVA
and optimum parameter values have been determined. Finally the process has been
verified by conducting experiments at selected combination of optimal parameters.
