Optimizing the Friction Welding Process Parameter to Obtain the Maximum Tensile Strength in AA 2024 Grade High Strength Aluminum Alloy Joints

Abstract:

Aluminum alloys are widely used in engineering structures and components where light weight or corrosion resistance were required. Friction welding is classified as a solid-state welding process where metallic bonding is produced at temperatures lower than the melting point of the base metals. Friction time, friction pressure, forging time, forging pressure and rotation speed are the most important parameters in the friction welding process. The Response Surface Methodology (RSM) is used to optimize the process parameter and also useful in developing a proper approximation for the right functional relationship between independent variables and the response variable that may differentiate the nature of the joints. The empirical relationships are developed with the help of ANOVA design matrix to obtain the maximum tensile strength in the joints. The integrity of the joints are evaluated by Optical Microscopy (OM) and Energy Dispersive X-ray Analysis (EDAX) in this research work.
