Abstract
A study on the fatigue behaviour of friction stir butt welds of 3mm thick 6082-T6
aluminium alloy was carried out. Monotonic tensile and cyclic tests of welded joints and base
material were performed to understand the influence of the welding process on the static and fatigue
properties. Microhardness profiles were measured and fatigue crack growth curves were determined
for cracks growing in different locations of the weldments. Friction stir material exhibited lower
strength and ductility properties than the base material. However, an enhanced crack propagation
resistance is observed.
