Purpose: Friction welding is found to be a suitable candidate for joining the dissimilar materials. Numerical model would be helpful for proper selection of processing conditions. In the present work, a thermo-mechanical model has been developed using finite element method based software. Design/methodology/approach: Friction welding process is characterized of thermomechanical phenomenon, which is highly complex in nature. Thermo-mechanical model is considered as highly nonlinear due to the interaction between the temperature fields and time dependent on the material properties. The numerical model is subject to certain assumptions and boundary conditions. Findings: The numerical investigation was carried out to predict the temperature distribution, heat flux, the axial shortening and stress on the friction welded titanium joints. Research limitations/implications: Leading aerospace manufacturers are exploring the joining of titanium to titanium for aerospace applications. The approach is time saving and it is supposed to have a promising future in automotive and nuclear fields.
