“…Therefore, it is necessary to study the joining technique that can ensure high reliability. To obtain a high-quality joint between aluminum and steel, several welding processes such as laser beam fusion welding [5][6][7], dual-beam laser welding [8], and laser beam welding with pressure [9][10] have been investigated so far. However, fusion base metal could bring a large number of intermetallic compounds in the laser beam fusion welding and dual-beam laser welding process.…”

“…Furthermore, these processes have the disadvantage of severe heating and cooling cycles which can result in the formation of brittle cast structure, porosity and large amounts of intermetallic phases (Fe n Al m ) that have a detrimental effect on the mechanical properties of the joint. [1][2][3][4][5][6][7] Brazing has also been used as a tentative process to join Al and steel. Strong joints have been formed using a eutectic Al-Si brazing alloy; however, holding time must be kept as minimum as possible to avoid the formation of a second, more fragile Fe n Al m intermetallic layer.…”

The present study investigates the effect of joining parameters on the microstructural and mechanical characteristics of dissimilar friction stir spot welding (FSSW) between AA 1050 Al and 22MnB5 hot stamped boron steel. Mechanical performance has been evaluated by shear and microhardness testing. Optical microscopy has been used to investigate the microstructure generated in the different FSSW regions. A macrostructural examination has revealed the creation of mechanical interlocking in the Al steel connections. No volumetric defects or any other imperfection has been found in all FSSW connections. Shear failure load has increased with increasing both tool rotational speed and plunge depth for all FSSW connections. Higher plunge depth has improved the mechanical interlocking between lower and upper sheet due to the formation of a larger secondary flash. Encouraging results have been obtained using coated WC-Co tools in terms of durability and joint performance.
