Friction Stir Welding (FSW) is a type of solid-state welding that is used in many different industries. One of the most important applications of FSW in the railway industry is the welding of train bodies. The main process of FSW is due to the creation of heat through friction between the tool and the workpiece, which depends on factors such as the parameters of the welding process, such as rotational speed, tool displacement speed, and so on. It is important to check these parameters because the heat required to connect the parts must be within a certain range so that the welding quality is not compromised; Therefore, the study of the temperature distribution of heat generated in this welding process is important. Numerical methods such as finite element method or finite volume method can be used to predict temperature behavior during FSW welding process. In this study, the effect of different parameters on the heat generated in FSW welding has been investigated. The equation governing heat transfer is considered to be both parabolic and hyperbolic, and a study has been conducted on the connection of two Non-homogeneous metals by the FSW method. The numerical method used in this research is the finite volume method which has been applied by coding in MATLAB software. Increasing the values of axial force, rotational speed and tool radius increases the temperature and increasing the speed of the tool reduces the temperature. Also, the results of the hyperbolic equation are slightly different from the parabolic ones. Finally, a user panel is designed to predict the temperature of the workpiece during the process with the ability to change various parameters, which can be a guarantee for selecting different welding parameters.
