Joining of lightweight dissimilar materials by friction stir spot welding (FSSW) provides numerous advantages over conventional welding methods such as resistance spot welding and self-piercing rivets. However, the keyhole left behind by the tool is a major drawback in FSSW, as it acts as a stress c...
