Prediction of relationship between angular velocity to the pitch line velocity (ω/v) on tensile strength of friction stir welded AA2014-T6 Aluminium alloy joints

High-strength aluminum alloys, such as the 7xxx and 2xxx series, are well suited for components and structures. It includes a greater strength ratio and is typically used in fabrication of fuselage and wing skins. AA2014 is difficult to join using a fusion welding process because of its high thermal...
