Description
Tensile testing was used to characterise and compare the fracture locations and their influencing factors for a number of friction stir welded aluminium materials (AA-1050, AA-2017, AA-6061). Friction stir welding was carried out on sheets of thickness 5 mm of AA-1050-H24, AA-2017-T351 (Al, 0.52%Si, 4.29%Cu) and AA-6061-T6 (Al, 0.62%Si, 0.9%Mg). Hardness distributions were measured across the joints. Tensile testing was carried out to fracture and fracture locations were expressed as the distance from the weld centre and whether on advancing or retreating side of the weld. Strain distributions in the joints were measured. Welding parameters were varied to produce joints with and without defects to investigate the effects of defects on fracture locations.
