Friction Stir Welding of AA 6083: An Integrated Engineering Study: Experimental Analysis, Simulation, Retrofitting, and Optimization—A Reference Project Model for Engineering Students

This study validates the load-bearing capacity of a retrofitted FSW tool used on a vertical milling machine for welding AA 6083 alloy in micro-industry settings. Axial and lateral forces on the tool were estimated through manual calculations and verified using finite element analysis (FEA) in ANSYS 11. The simulation assessed stress distribution and deformation, ensuring the tool design withstands operational loads. A load cell was integrated into the retrofit assembly to capture real-time welding forces, which were compared with FEA results for validation. The close agreement between simulated and experimental data confirmed tool reliability and the mechanical feasibility of the retrofitted system. This approach demonstrates a cost-effective solution for FSW implementation in small-scale industries.
