Accepted 3 February 2017 The present investigation work focuses on friction stir welding process in which influences of Available online operating parameters have been studied on friction stir welded butt joints. The FSWed joints 6 February 2017 Keywords specimens have been produced by experimentation at three levels of tool traverse speed and FSW tool rotational speed keeping input force and tool tilt angle constant. Mechanical properties AA5083 and microstructure of welded joints have been investigated in the present study. Change in the Micro-hardness microstructure at different zones which transforms the mechanical properties of welded joints Microstructure was due to the asymmetrical flow of material and thermal cycles around the pin. The second Ductility phase beta grains are formed as the very high temperature reached due to input parameters Tensile strength combinations. Traverse speed TS and tool rotational speed TRS are taken in a range of 16- 40 mm min and 500-1400 rpm respectively. The best combination of parameters results in higher tensile strength which is well supported by .
