Review on Optimization Techniques such as DOE and GRA used for Process Parameters of Resistance Spot Welding

Manoj J. Ghag | M. Veerabhadra Rao ^[2]

Abstract: In order to maintain the optimum utilization of the resources, time and economy, the various process parameters and their levels are optimized in order to get the output quality product or process. Many industries such as automobiles, domestic appliances, air craft and space craft fabrication having the resistance spot welding as a major sheet metal joining process. As the spot welding involves interactions of thermal, mechanical, electrical and metallurgical phenomenon, controlling the welding parameters plays an import role on the quality of the weld. Resistance spot welding is a high speed process, where in the actual time of welding is a small fraction of second and it is one of the cleanest and most efficient welding processes. Resistance spot welding has ability to join the variety of materials and complicated shapes with high accuracy and great precision. The Taguchi Method is used to determine the optimum process parameters. At the design stage, for the purpose of designing and improving product quality, the Taguchi Method is a systematic application of design and analysis of experiments.
