Abstracts: Friction stir welding (FSW) is a new solid state welding process for joining metallic alloys and it is useful in several industries such as aerospace and automobile for joining aluminium, magnesium and copper alloys. The various parameters such as rotational speed, transverse speed, and tool tilt angle play important roles in FSW process and the quality weld. The aim of this study is to know the relation between the effect of different transverse speed and tool pin profile on the weld quality of AA6082 (HE 30) aluminium. The current studies also aim to understand mechanical properties during the FSW. The mechanical properties of FSW AA6082 will be measured by tensile testing and % elongation and finding out the defects in welded plates by the use of NDT-Radiographic testing method. We have used methods of Design of Experiments (22) in order to find relationship between independent and response variables.
