Abstract

Friction stir welding process is considering one of those solide state welding techgniqe. FSW process has high residuel stresses, distorsion and corrosion resistance. uktrasonic assisted FSW was optimized using the taghuci techniqe to determine the oprtimum condition of process paramters. Effect of process parameter like the vibration amplutude, traverse speed, and tool rotional speed on the oerformance was ansylzied to achive the maximum joint efficiency. anlysis of variance test was demonstrated using mintab sotware to determine the imoirtant of the process prameter that affect the ultimate tensile strength of FSW joints by detetming the contribution percentage if each paramter. the infunese kf uktrasonic vibration on the UTS is more orofound at high welding speeds, wher acoustic softening can privide FSW process with additional softening and therby, the material flow improved. Taghci analysis has shown that the optimum cobdtion observed for a welding speed of 80m/min, rotional speed of 809rpm, and amplutude of 20um.
