Friction stir welding (FSW) is relatively a new welding method where heat generated by friction is used toforge components together under an axial force. In this method, the generated heat does not exceed the material meltingpoint, instead the material is heated to its forging temperature and is stirred together by a rotating tool. Since theinvention of FSW, this technique has been mainly used for welding aluminium plates together for butt and lap jointconfigurations. In this work, double sided friction stir welding was performed on AA 6061 plates of 12 mm thickness atrotational speeds (1000, 1400, 2000 rpm), weld speed (20, 28, 40 mm/min) with the conical tip tool. Tensile strengthanalysis has been carried out on nine sets and process parameters are optimized by using TOPSIS method. The mostsuitable set of parameters is found at tool rotational speed (TRS) of 1000 rpm and weld speed (WS) of 40 mm/min.
