Temperature Determination of St-Al Joints During Friction Welding

The joining of dissimilar materials is of great importance in industry. Especially, if it is used as the lightest part of the machine parts, materials such as aluminum and magnesium can be joined with steels. Friction welding is one of the methods getting higher share among the other welding methods. In the process, heat is generated by conversion of mechanical energy into thermal energy at the interface of the work pieces during rotation under pressure. Some of the advantages of friction welding are high material save, low production time and being possible of welding of parts which are made by different metals or alloys. Friction welding can also be used in order to join the components that have circular or non circular cross sections. In this study, stainless-steel and aluminum materials which is the example material was used in the friction welding experiments. The temperature distributions are experimentally obtained in the interface of joints that is formed during friction welding of joints having same geometry. This study was made using thermocouples at different locations of joint-interface.
