In the automotive industry, one of the main objectives is to reduce vehicle weight in order to decrease energy consumption. Replacing steel with aluminum is an effective way to achieve weight reduction, but it represents a major challenge in maintaining mechanical properties. Modelling hybrid aluminum–steel assemblies has therefore become important to reduce the environmental impact of the automotive industry. A way to introduce hybrid aluminum steel assembly is the Resistance Element Welding (REW). Comparing the flux distribution in these two assemblies (RSW and REW) is therefore essential to characterize the temperature field during the assembling process.
