Application of taguchi method for the optimization of resistance spot welding process

Abstract EN

This paper reports on an investigation of the effect and optimization of welding parameters on the tensile shear strength in the resistance spot welding (RSW) process.

The experimental studies were conducted under varying electrode forces, welding currents, electrode diameters, and welding times.

The settings of welding parameters were determined by using the Taguchi experimental design method.

The level of importance of the welding parameters on the tensile shear strength is determined by using analysis of variance (ANOVA).

The optimum welding parameter combination was obtained by using the analysis of signal-to-noise (S / N) ratio.

The confirmation tests indicated that it is possible to increase tensile shear strength significantly by using the Taguchi method.

The experimental results confirmed the validity of the used Taguchi method for enhancing the welding performance and optimizing the welding parameters in the resistance spot welding process.
