Abstract
The primary goal of this study is to implement the Rotary Friction Welding (RFW) process to join similar Ti6Al4V welds. The experimental procedure involves the deliberate manipulation of input parameters, including rotational speed, friction pressure, and friction time, through the utilization of Taguchi's L9 orthogonal array methodology. This approach is facilitated using the MINITAB software to generate a visual representation of the response chart. The primary focus of the investigation centers on the assessment of the Ultimate Tensile Strength (UTS) of the welded joint, serving as the selected output parameter. The central objective is to identify the optimal RFW conditions that lead to the highest achievable UTS. Furthermore, by conducting thorough statistical analysis of variance (ANOVA), the most influential process parameter is identified and analyzed. The concluding phase involves the development of a comprehensive regression equation governing the UTS for the titanium alloy. The accuracy and reliability of this equation are then validated through rigorous experimental tests and the corresponding observed values.
