Effect of Axial Force on Mechanical and Metallurgical Properties of Friction Stir Welded AA6082 Joints
In this investigation an attempt has been made to highlight the influence of axial force on the mechanical and metallurgical properties of friction stir welded aluminum alloy AA6082-T651 joints. The axial force is varied from 3 kN to 8 kN on the surface of the base material. Tensile test, macrostructure and microstructure tests were performed on all the welded specimens. SEM was used to know the behavior of the fractured surface of the tensile test specimens. It is found that the joint fabricated at 6 kN axial force has higher tensile strength and good metallurgical properties.
