چکیده مقاله:

Friction Stir Welding (FSW) is a solid-state welding technique known for producing lower residual stresses compared to fusion welding. This study focuses on the finite element (FE) modeling of the process for the homogeneous aluminum alloy ۶۰۶۱, with separate thermal and mechanical analyses. The thermal analysis was carried out using a DFLUX subroutine, which provided a temperature distribution that was experimentally validated by thermocouple measurements. The computed temperature profile was then used in the mechanical analysis. To assess the effects of welding parameters such as advancing speed and rotational speed on the maximum welding temperature and residual stresses, an experimental design was developed using the response surface method, with Minitab Statistical Software ۲۲. The results show that, at a constant rotational speed, both temperature and residual stress decrease with increasing advancing speed, whereas residual stress increases with higher rotational speeds.
