During friction welding, temperature, stress, strain, and their variations govern welding parameters, and knowledge of them helps determine optimum parameters and ways to improve the design and manufacture of welding machines. The finite element method was used to model the titanium–tungsten pseudoalloy joint. Coupled thermomechanical model was built, the Johnson-Cook equation was used to define material properties. The calculated results of temperature distribution were in good agreement with measured ones. The numerically calculated results for the shape of the welded joint also showed a good fit with the experimental observations. The effects of friction coefficient variation with temperature are discussed.
