“…FSSW parameters are evaluated, namely, TRS, PR and DT effect on the fabricated joint properties (conductivity, lap shear and flexural strength, and hardness). Factors and levels selected for performing experiments are based on experts’ advice and consulting literature. − A total of 27 experimental conditions (each experimental condition is repeated twice) were considered by considering three factors operating at three levels (TRS: 1500, 1900, 2300 rpm, PR: 4, 8, and 12 mm/min, and DT: 8, 16, and 24 s). The sheets to be welded are cleaned and cut to the required size.…”

Due to their contrasting physical properties, joining materials like copper and aluminum has always proven difficult. The disadvantages of traditional joining methods include additional weight, solidification problems, and energy waste. Friction stir spot-welding (FSSW) was utilized for joining copper and aluminum in order to get around these difficulties. This study illustrates that friction stir spot-welding (FSSW) produces joints between incompatible copper and aluminum alloys with better mechanical and electrical properties. The numerous FSSW parameters play an important role in deciding how well the welded joint performs. Tool rotational speed (TRS), plunge rate (PR), and dwell duration (DT) are the study parameters. During manufacture, a case-hardened H13 tool was used to lap-joint AA 6061 T6 hot-rolled aluminum flat strips with C11000 copper strips while operating at three different levels of TRS, PR and DT. SEM analysis was utilized to investigate the interface region and bimetallic interface of the joints. In order to demonstrate modifications in the grain-related characteristics, the joints were examined for electrical conductivity, mechanical strength (lap shear, bending, and microhardness test), and analysis of the microstructure at the weld zones. The outcome demonstrates that other factors, such as plunge rate, dwell time, and tool rotation speed, had the greatest impact on the joints' electrical conductivity, mechanical strength, and microstructure.
