Abstract
Friction stir welding (FSW) is considered as the new joining technique which does not involve fumes like any traditional joining techniques. The attainment of good weld depends on proper combination of FSW parameters, and this combination varies with the materials that are being welded. The tool rotational speed is known as the most critical parameter towards the generation of heat required to produce the weld in friction stir welding. This parameter plays an important role in restructuring the stir zone. The variation of this parameter may yield certain results which are dependent on the type of materials being welded. This paper reports on the impact of the rotational speed variation on the tensile properties of AA6082-T6 joints. The rotational speed was varied while keeping all the other welding parameters constant. The analysis was performed comparatively on the specimens that were sampled from different locations of the joint. The joints produced through the rotational speed of 600 rpm showed good tensile properties compared to joints produced through other rotational speeds.
