主　　题：Research on Resonance Mechanism of Arc-ultrasonic Arc 

摘      要：As a transmission medium, welding arc can be modulated to emit ultrasonic energy by exerting high-frequency electric current. The frequency of exciting electric current has notable influence on the signals recorded by the sensors and the metallographic structures of the welds. The resonance phenomenon of arc-uitrasonic has been found in the experiment. Both the resonance mechanism and the distribution of resonance frequency are discussed by the bui|t vibration equation.
