A Study Into Effects of Different Parameters on Mechanical Properties in Friction Stir Welding of AA 2024 Aluminium Alloy

Abstract

In this study AA2024 alloy, which is used especially in aircraft body, wings and automotive industry due to its lightness, workable aspect, high corrosion resistance and durability, was welded with stir friction method, and fatigue, hardness, bending and tension experiments of the joints obtained were conducted. Welding progress speed of the 4 mm thick sheets and stir tool rotation were determined to be the variable parameters. These parameters were taken as 20 mm shoulder width, 1000 rpm traverse speed, 1500 rpm, 2500 rpm and the progress speed was taken as 120 mm/min and 200 mm/min.
