对6061-T6铝合金搅拌摩擦焊接头的实时测温结果表明，主轴转速对刀具-工件界面温度的影响大于行进速度。这些工艺知识允许将主轴速度用作保持焊接温度的控制方法。然而，并不是所有的铝合金都具有主轴速度优势。对铝合金2024-T3、5083-H116和7075-T6进行了其他参数研究，其中5083合金是唯一一种主轴速度或行程速度对界面温度都没有显著影响的合金。在合金中，不仅平均界面温度不同，温度变化的幅度也不同，这取决于合金和所选的焊接参数(主轴或移动速度)。
The real-time temperature measurement of aluminum alloy 6061-T6 friction stir welds (FSW) has shown that spindle speed has a greater influence on the tool-workpiece interface temperature than travel speed. This process knowledge allows for spindle speed to be used as a control method for maintaining weld temperature. However, spindle speed dominance has not been shown to be true for all aluminum alloys. Additional parametric studies have been performed on aluminum alloys 2024-T3, 5083-H116, and 7075-T6, where alloy 5083 is the only alloy of which neither spindle speed or travel speed has a significant effect on the interface temperature. Among the alloys, not only does the average interface temperature vary, but also the amplitude in temperature change, depending on the alloy and chosen weld parameters (spindle or travel speed).
