Abstract
Friction Stir Welding (FSW) is a solid state joining technique which is universally used for joining of aluminium alloys in marine, aerospace, automotive and many other applications of commercial importance. In this present study, the effect of FSW parameters on the weldability of dissimilar aluminium alloys such as AA2014 and AA6061 were investigated. The two plates were aligned perpendicular to the rolling directions and the welding was carried out. The main objective of the experiment is to find out the maximum tensile strength. The experiments were conducted on a milling machine. Three factor three levels Central-Composite matrix in Response Surface Methodology (RSM) is employed to carry out the experimental investigation. The “Design Expert 8.0”, software was used for regression and graphical analysis of data collected. ANOVA was used to check the validity of the model. A designed FSW experiments were carried out to get a high strength welding by controlling the rotational, welding speed and tool pin diameter. The tensile tests were carried under tension at room temperature in order to analyze the mechanical response.
