| Abstract Scope |
The quality of friction stir spot welding (FSSW) is heavily influenced by the selection of optimal welding parameters, especially tool rotational speed and dwell time. These factors affect heat generation, impacting the structural integrity of the joint. This study investigates how tool rotational speed affects temperature generation and energy dissipation in AA6082-T6 aluminum alloy. Utilizing finite element analysis (FEA), the research examines variations in equivalent plastic strain and stress at the welding process's end. Results indicate that higher speeds, around 1000 rpm, generate maximum temperatures of 265°C, which enhances metal flow but increases plastic strain and stress. Conversely, lower speeds, like 400 rpm, yield only 140°C, insufficient for optimal metal flow (greater than 160°C).The 600-rpm speed aligns closely with high-speed conditions, emphasizing the need for careful tool speed selection to enhance manufacturing sustainability. FEA predictions were validated against experimental data, highlighting the reliability of this approach for modeling the FSSW process. |
