Rotary friction welding is one of the most economical and efficient production methods for joining similar and dissimilar materials. It is widely used with metals and thermoplastics in a wide variety of aviation, transport, and aerospace industrial component designs. Individually, mild steel to mild steel and copper to copper are normally easy to weld by fusion welding methods, but the joint of mild steel to copper can be extremely difficult due to the differences in the two materials' melting temperature, density, strength, and thermal conductivity. Thus, these kinds of problems can be eliminated by a solid-state friction welding technique. Hence, the current study attempts to understand the friction welding characteristics of mild steel-bronze dissimilar parts. This study looks into the influence of process parameters, which includes friction pressure, upsetting pressure, and upset time on the axial shortening, hardness, microstructure, and tensile properties of the welds. The optimum parameters for upset time, upset pressure, and friction pressure necessary for welding were obtained. Finally, the obtained mechanical properties results were commented on the light of optical microscopy.
