Experimental Investigation on the Effect of Tool Rotational Speed on Mechanical Properties of AA6082-T6 Friction Stir-Welded Butt Joints.

In this study, the effect of tool rotational speed on mechanical properties of AA 6082-T6 aluminum alloy was investigated. Different welded joints were produced by using four rotational speed (500, 710, 1000 and 1400 rpm) and constant welding speed at 80 mm/min. Mechanical properties of the welded joints were evaluated by hardness measurement on the transverse section and tensile testing. The experimental results show that the tool rotational speed has a significant effect on weld mechanical properties of joints. [ABSTRACT FROM AUTHOR]
