The paper presents a comprehensive review on dissimilar friction stir welding (FSW) of Al to non-Al metallic materials, wherein the combination of Al–Mg, Al–Cu, Al-steel and Al–Ti are covered. The summary revealed that FSW is observed as one of the most feasible solutions in the family of welding in case of dissimilar materials combinations of Al to non-Al metallic materials. The challenges such as the formation of intermetallic compounds, defects, and degradation of mechanical properties at the joint area are extensively managed in the case of dissimilar FSW compared to dissimilar conventional welding.
