Abstract
Friction stir welding is a recommended green process that can replace other assembly techniques.
FSW process reveals good mechanical properties, good corrosion resistance and good economic value. For the
purpose to evaluate combinations of operating parameters and estimating the welded joint quality, mathematical
relationships were carried out using a design of experiment on three levels of rotational speed, feed rate and tool
tilt angle. The models allow micro-hardness prediction in the different FSW joint zones of AA3003 aluminum
alloy. The interaction of the factors shows that a decrease in rotational speed, angle of inclination and an
increase in feed rate leads to a decrease in temperature and good microhardness. A ‘W’ shape profile of
microhardness was shown cross the section, indicating an efficiency equal to 88% and 79% in the nugget and
the heat-affected zone successively, compared to the base metal. Contrary any deviation of welding interval
may cause various defect such as tunnel voids, ‘kissing-bond’ defects and crack-like root flaws.
