Abstract

The optimization of parameters considering multiple performance characteristics to minimize power consumption in Resistance spot welding (RSW) process for GI sheet using the Grey relational analysis (GRA) is presented. Performance characteristics including Current, Weld time, Electrode force and Thickness are chosen to evaluate the machining effects. This all the process parameters are closely correlated with the selected performance characteristics in this study are the hold time, squeeze time, and electrode tip diameter. Experiments based on the appropriate L27 OA are conducted first. The coefficient and grades according to GRA are evaluated using normalized experimental results of the performance characteristics. The Analyses Of Variance (ANOVA) are conducted to identify the most significant factor affecting the spot welding performance. Process parameters after optimization are simultaneously leading to maximum tensile-strength and minimum Nugget diameter will be then verified by confirmation experiment.
