Abstract

Resistance spot welding of aluminum alloy 6082T651 is used to spot-weld the peripheral flange of the well member to the faceplate section of fuel rail in a diesel engine. The interlayer of SS304 having 0.5 mm thickness was introduced into the lap joint, an effect of which was the focus of the investigation. It is the need of modern automotive industries toward industrial fabrication with improved mechanical properties of thin aluminum sheets. This research paper summarizes work on the welding current, electrode force and welding time as input parameters, whereas failure load and nugget diameter were output parameters for this work. The range of electrode force was 1447–5653 N; the welding time was 0.6–7.5 cycles, and the welding current was 20–31 KA, during the performance of the experiment. A design matrix was generated by employing a central composite design (CCD) for experimental work. Effects of the welding process parameters on failure loads and nugget diameters were observed using ANOVA and then formulated by two separate equations.
