Abstract :
In this paper a very sensitive device allowing the measurement of the forces exerted on an electrode by an electric arc is presented. The device principle is based on the use of a piezoelectric transducer. The calibration of the device is explained and experimental results are presented concerning the force exerted on various electrode materials (Ag and AgSnO2) for cathodes and anodes. Force measurements have also been realized for various cover gases (air and argon) and for various arc current pulse durations
