Influences of welding speed on mechanical properties of friction stir welded joints of AA2014-t6 aluminium alloy

Abstract

The current work is concentrated on the influence of traverse speed on mechanical properties of Al alloy (AA2014), by trailing one of the process parameters and while others were kept constant. The joint fabricated from a rotational speed of 1500 rpm, welding speed of 40 mm/min, shoulder diameter of 6 mm and tilt angle of 1.5° yielded superior tensile strength compared to their counter joints. Due to the formation of defect-free, balanced material flow, uniform distribution of precipitates in the processed region.
