Abstract
Friction stir welding has made remarkable progress since its invention in 1991, for welding aluminum alloys. Although the process has many benefits, there are also drawbacks, one of them being the risk of root flaws in single sided welds. One of the most promising ways to avoid these is to use a double-sided or bobbin tool, as this removes the root region. The bobbin friction stir welded 6 mm thick AA1100 has been done successfully which widened the application of BFSW on AA1100. Optimization via RSM used for analyzing the influence of both spindle and welding speeds on the mechanical properties of the AA1100 weld. The conclusions is drawn from the both experimental and optimization of both spindle and welding speeds had influence the tensile properties of the weld and the average hardness at stir zone weld region. The results show that increasing the spindle speed and welding speed can lead to an increase in tensile strength and average hardness. Specifically, for every one unit increase in spindle speed, the predicted tensile strength is expected to increase by 0.03 units, and for every one unit increase in welding speed, the predicted tensile strength is expected to increase by 0.04 units.
