| Abstract | ||||
| This paper presents a comprehensive simulation study of Friction Stir Welding (FSW) applied to super duplex stainless steel SAF2507 (UNS S32750)[1]. Two numerical methods, coupled Euler-Lagrange and smoothed particle hydrodynamics, are employed to model the FSW process, [2, 3]. The simulations include essential welding parameters: welding velocity, rotation velocity, tilt angle, and axial force, [4]. To ensure model accuracy and reliability, the results are rigorously validated against experimental data. Two validation methods are utilized, enhancing the robustness of the simulation outcomes. This research contributes valuable insights into FSW processes for super duplex stainless steel SAF2507, serving as a dependable foundation for further exploration and optimization of welding parameters in manufacturing applications. | ||||
