Abstract

Dissimilar joints of AA5083 and pure Cu joint are successfully produced and compared by friction stir spot welding and modified friction stir clinching with intermediate layer of Zn interlayer for the first time. Self-reacting behavior of Zn is observed to obtain sound welds resulted from intermixing in stir zone (in FSSW), refilled zone (in MFSC) and brazed zone (in both FSSW and MFSC). MFSC is used to fill the cavity of keyhole that in turn increased 40% strength of dissimilar Cu–Al joints. Presence of lamellar eutectics in brazed zone and intermetallic compounds such as Al2Cu, Al4Cu9, CuZn5 and Cu4Zn in weld zone are confirmed in Cu–Al MFSC joints.
