| Abstract: | This paper is concerned with application of the voltage-current floating evaluation method for determining the friction torque of continuous drive friction welding. Electric voltage and current of the main motor are monitored in real time and synchronized. Based on the analytical model with exponential function behavior, both transitional and steady-state drive friction welding have been made use of in practice. |
