Abstract

The development of the welding process has provided an alternative improved way of satisfactorily producing aluminium joints, in a faster and reliable manner. The aim of the present work is focused on the comparative study on the mechanical and dry sliding wear (tribological property) behaviour of welding joint fabricated by friction stir welding (FSW), tungsten inert gas (TIG) and metal inert gas (MIG) on 6 mm thick aluminium alloy 7075 T6. The samples were fabricated, and their testing was carried out as per the ASTM standards. The maximum tensile strength (242.3 MPa) and impact strength (12 J) and join efficiency (44%) were obtained for FSW joints, whereas these properties for TIG and MIG welded joints were on the lower side. The elongation at the break was found to be higher for FSW joint as compared to that of TIG and MIG joints. The minimum specific wear rate was obtained for FSW joint as compared to that of TIG and MIG joints. Microstructure results show that the smaller grain sizes were obtained in the weld centre of FSW, whereas grain growth was observed in TIG and MIG welds. FSW joints were better than TIG and MIG joints.
