Description
Summary:Resistance spot welding process parameters are optimized to improve spot weld quality. The experimental studies are conducted under varying force of electrode, welding current flow and its time duration. The spot weld quality characteristics are shear tensile strength and direct tensile strength has been considered. Signal to noise ratio was used to establish optimal process parameters. To authenticate the contribution percentage of experimental results against specified confidence level ANOVA was used. Verification trials show that it is feasible to improve the quality characteristics considerably. The investigational repercussions proved the effectiveness of the applied Taguchi method for improving spot weld quality.
