Experimental study of friction stir welding of AA 6061 & AA 5083 using taguchi technique

Friction stir welding, a solid state joining technique, is widely being used for joining Al alloys for aerospace, marine automotive and many other applications of commercial Importance. FSW trials have to carry out using a vertical milling machine on Al 6061 AA5083 alloy. The tool geometry was carefully chosen and fabricated to have a nearly flat welded interface. The objective of this research is to quantify the relationship between spindle speed, travel speed, and tool tilt angle parameters for friction stir welding (FSW) at high spindle speeds (1200rpm-4600rpm) to optimize the rockwell hardness testing of Al6061 and AA5083 alloy. Taguchi design is used for the current research work. This technique provides straight evaluation of the influence of the investigated parameters on the friction stir welding outcomes i.e. Rockwell Hardness.
