Rolling ring is one of the most important metal forming processes for fabricating rounded geometries with optimal mechanical properties in the environmental direction. The ability to fabrication of two-layer rings can be used in many industries. One of the properties of these rings is the lightweight with high strength or wear resistance along with high strength. In this research, we have tried to study the ring rolling process of the bonded two-layer ring and its effective parameters during the process using finite element analysis by ABAQUS software and experimental test. The rings are attached for process simulation and empirical testing. In the end, a ring of two-layer of pure Lead 99.99% and Tin 63% was formed. Based on the results obtained from this analysis and according to the dimensions and parameters considered for performing the process, the tension created in the bonded two-layer ring is between the values of 1.146×105-1.800×107Pa and it has a strain of 0-1.187. Its contours of strain and stress are represented to better understand the process. Considering the results obtained from the simulation of the process, an experimental study of the ring rolling process of the bonded two-layer ring was conducted. The method of this study was first designed by the modeling software to design the casting model and then by designing the test, the number of tests required for the experimental test was obtained and then the number of materials needed for the test was calculated. After testing, the mechanical and metallurgical properties of rolled double rolled rings were investigated.
