Abstract

Welding technique is a method used in order to join various materials in manufacturing methods. Friction welding in the technique is one of the various application methods. The method has been in widespread use since 1950. The most important advantages of the method are its easy application, the savings on materials and energy. In the process, heat is generated by conversion of mechanical energy into thermal energy at the interfaces of the components during rotation under pressure. In this study, the relationship between mechanical and heat energy was carried out mathematically. AISI 1040 medium carbon steel, which is the example material, was used in the experiments and the models. The total heat energy, the heat loss and the temperature field in joints which depend on the welding time were examined on friction welding of various parts having various geometries. The examination was carried out using Quick-Field program due to the harmony with the experimental results and its easy application. As a result, different data were evaluated for obtaining material properties and operating conditions, and the obtained results were compared with previous studies. Then, the most suitable conditions for time, material and energy were acknowledged on the future applications of friction welding.
