Friction stir welding (FSW) is one of the solid state welding coming from a combination of heat and pressure in order to obtain the joining by stated process. However, there is very lack of information regarding to the studies of Bobbin Friction Stir Welding (BFSW). Therefore, this studies are to investigate the mechanical properties of thick and thin materials welded focusing on BFSW technique. The material that used for this study was Aluminum Alloy 1100 with the thickness 3mm and 6mm. In the meantime, the design of tool might give a huge contribution to the final welded product. The parameters that has be applied for this study are the spindle speed and welding speed. All of the welding process using CNC Milling Machine. There is only 2 set of parameters that used which are 900 rpm and 310 mm/min for spindle speed and welding speed. The other parameters are 1440 rpm for spindle speed and 190 mm/min for welding speed. The final product are testing by using tensile test, micro hardness, and XRD analysis. Result of this testing shows the properties of the welded materials by applying set of parameters that have been decided. By the end of this studies, thin materials not acquire the suitable parameters since the final product still showing sign of defect such as open tunnel and entry issues. Moreover, thin material are rarely to complete the joining process since specimen tend to broke during experiment. While for thick material, the parameters can be accepted because of the tensile, hardness, and XRD analysis. Future work studies still need to be conducted in order to overcome the problem that occur on thin materials. One of the idea are by studying the influence of tool design in BFSW.
