Abstract

The weld quality assessment in friction stir welding depends on the choice of suitable weld parameters. Rotational speed is one such parameter. The study utilizes a computational fluid dynamics model to examine the influence of various rotational on the workpiece and weld interface temperature. The workpiece selected for this study is an Aluminium Alloy 6061, while the tool employed is a truncated conical pin tool featuring a conical shoulder in a lap joint configuration. The maximum weld interface temperature rises linearly with a relatively constant slope from 500RPM to 2900RPM rotational speed, according to the study. With increase in rotational speed, most of the heat created is moved away to the trailing side of the workpiece due to material flow; therefore, heat transferred down the thickness is minimal. The validation of the findings of this investigation is accomplished through a comparative analysis with data that has been previously published. Given the aforementioned facts and conclusions, friction stir welders can enhance their understanding of the influence of rotational-speed on the quality of welding.
