Abstract: The present disclosure provides a system and method for measuring energy conversion efficiency of an inertia friction welding (IFW) process in a non-contact manner. The system includes an IFW machine, a Hall sensor, a data acquisition module, a processing module and a stabilized direct current (DC) power supply. The stabilized DC power supply provides electrical energy for the Hall sensor. The Hall sensor is provided beside a flywheel of the IFW machine, so that the flywheel is within a detection range of the Hall sensor. A magnet is provided on the flywheel. The data acquisition module acquires a Hall electric potential change caused by a relative movement between the magnet and the Hall sensor during the IFW process, and transmits the Hall electric potential change to the processing module to calculate the energy conversion efficiency of the IFW machine.
