The present study is based on an investigation of the effect and optimization of welding parameters on the tensile shear strength in the Resistance Spot Welding (RSW) process on A5052 aluminium alloy. The experimental studies were conducted under varying welding current, welding time and electrode forces. The settings of welding parameters were determined by using the Taguchi experimental design of L9 Orthogonal array method. The combination of the most favourable welding parameters have decided by using the analysis of Signal-to-Noise (S/N) ratio. The confirmation test performed clearly shows that the combination of the suitable welding parameters improves the tensile shear strength of the joints. Thus, the experimental results confirmed the validity of the used of Taguchi method for improving the welding performance and optimizing the welding parameters in resistance spot welding operations.
