Abstract
In this present study, the impact of axial force on the mechanical properties of friction stir welded dissimilar aluminium alloy joint was investigated. Four different axial forces such as 4kN, 5kN, 6kN, and 7kN were used. The tool rotating speed and welding speed of 2000 rpm and 60 mm/min respectively was employed. The microstructure of various zones of weld joint was investigated and observed using an electron optical microscope. The hardness and tensile characteristics of welded joints were investigated in order to determine their mechanical behaviour. Mechanical findings demonstrated that joints created with a 6kN axial force produced satisfactory joints. The creation of grain structures with evenly dispersed and finely refined grains in the WSZ of the FSW joint and the appropriate level of heat generation are also discovered to be the primary causes of the perfect joints with superior mechanical qualities.
