Abstract Scope Resistance spot welding of similar AISI-1008 steel plates and dissimilar AISI-1008/Al-1100 alloy joints were carried out using a graphene nanoplatelets (GNP) interlayer and the underlying strengthening mechanisms has been discussed. Weld strength of the joints depends on the welding current/time used for the resistance spot welding. Comparison of the lap-shear strength was carried out for both the bare and GNP coated similar and dissimilar joints. An enhancement of ~63% and ~124% was reported at certain parameters for the similar and dissimilar joints respectively. Optical microscopy, SEM, XRD and Raman spectroscopy was used for microstructural characterization. Al-Fe rich intermetallics (IMCs) formation was reported at the interfacial zone of the dissimilar joints. Nugget size variation with the welding current was studied. Fractured surfaces were analysed and it was concluded that shear dimple and a mix of shear dimple and brittle fractures were dominant in case of similar and dissimilar metal joints respectively.
