Influence Of Factors for Friction Stir Welding of Aluminum Alloys AA5083 and AA6061 With Reinforcing Material in The Weld Line

Abstract

This research intended to explore the influence of parameters for filling of silicon carbide reinforced particles in the weld line for friction stir welding of aluminum alloy AA5083 and AA6061 as a guideline for enhancing the tensile strength in the weld line. Determining the variables were the tool rotation speed of 800, 1,000 rpm and the welding speed of 15, 30 mm/min. Statistical analysis showed that the tool rotation speed and welding speed significantly influenced the tensile strength at 0.05 level. The tool rotation speed had the highest influence on the tensile strength of the workpiece followed by the welding speed. Increasing the tool rotation speed will result in higher tensile strength of the workpiece, while decreasing the welding speed will result in higher tensile strength of the workpiece. The best factor affecting the tensile strength of the workpiece in this experiment was the tool rotation speed of 1,000 rpm and the welding speed of 15 mm/min., the highest tensile strength is 211.63 MPa.
