RESUMO

Heat transfer in friction welding of cylindrical tubes is considered in the present study and the governing equations are solved numerically using an explicit finite difference technique to determine the temperature field. The values of the radius ratio in the problem are selected as rr = 0.25, 0.50, and 0.75. Results show that the temperature of tubes increases with increasing radius ratio. In addition, as the generated heat is proportional to the interface radius, the temperature increases from the inner surface but drops slightly towards the periphery due to the convection effect. The temperature field is of a similar form for all values of the radius ratio, but the radial and axial temperature gradients change at certain amounts.
