Application of Response Surface Methodology (RSM) in Friction Welding AISI 1020 Grade Steel Joints

Abstract:

In this research work, the friction welding of AISI 1020 grade steel joints are fabricated to predict the minimum Vickers hardness in the joints. The response surface methodology was used to optimize the friction welding parameters in this study. RSM is a collection of mathematical and statistical techniques that are helpful for designing a set of experiments, analyzing the optimum combination of input process parameters, developing a mathematical model, and expressing the values graphically. Therefore, the response surface methodology has been utilized to optimize the friction welding process parameter with the help of ANOVA design matrix. The microstructures analyzed were carried out for the optimized condition joint.
