The purpose of this paper is describes a method of temperature monitoring in bonding interface during the rotary friction welding of dissimilar materials. As it is directly related to the mechanical strenght of the junction, its experimental determination in real time is of fundamental importance for understanding and characterizing the main process steps, and the definition and optimization of parameters. The temperature gradients were obtained using a system called Thermocouple Data-Logger, which allowed monitoring and recording data in real-time operation. In the graph temperature versus time obtained were analyzed the heating rates, cooling, determined the maximum temperature occurred during welding, and characterized every phases of the process. The system efficiency demonstrated by experimental tests and the knowledge of the temperature at the bonding interface open new lines of research to understand the process of friction welding.
