OPTIMIZATION OF WELDING PARAMETERS OF ELECTRICAL RESISTANCE SPOT WELDED 6082-7075 ALUMINIUM JOINTS USING THE TAGUCHI METHOD

In this study, aluminium alloys of AA6082 and AA7075 series were welded with resistance spot welding. Effects of welding current intensity, welding time, and electrode pressure on the tensile strength and microstructure were examined, and their optimized values were determined using the Taguchi method. While performing optimization, the L24 orthogonal array was used with the Taguchi method. With this array, the signal/noise (S/N) ratio became the determining factor in controlling the optimization results. Comparing the experimental procedures and analysis results, the results obtained from the real application and Taguchi analysis were found out to be similar.
