“…Referring to Figure 3(b), the average hardness of most regions of the FREWB and FREW joints are comparable, but the average hardness of the region near the nugget of FREWB joints is higher than that of FREW joints. A similar phenomenon was observed by Ma et al [24] when performing laser spot weld-bonding on Q195 steel, they reported that due to the decomposition of the adhesive, the nugget of the FREWB joints is enriched with carbon and resulting in an elevation of the hardness value.…”

A novel method called flat resistance element welding-bonding (FREWB) is proposed to join aluminium alloy to Q235 steel. The microstructure and mechanical performance of FREWB and flat resistance element welding (FREW) were investigated. The microstructure of the nugget was lath martensite. The heat-affected zone of the rivet could be divided into two zones according to the microstructure: the upper-critical heat-affected zone (UCHAZ) and the inter-critical heat-affected zone (ICHAZ). The microstructure of UCHAZ consists of martensite, and the microstructure of ICHAZ consists of martensite and ferrite. The failure mechanisms of the FREW and FREWB joints were analysed. Moreover, an analytical model was established to predict the variation of critical nugget sizes, which provided a relatively good prediction.
