A 3-D time-dependent numerical model for the analysis of a dc transferred argon arc is presented. The model allows to investigate the influence on the behavior of the arc and on the evolution of the temperature inside the anode of an external magnetic field induced by a current flowing in an external conductor. If the currents of the arc and of the external conductor have opposite directions, the magnetic fields mutually repel and the arc is deflected. Such a practice to obtain a deflected arc finds applications in surface treatment of metallic substrates.

Abstract
A 3-D time-dependent numerical model for the analysis of a dc transferred argon arc is presented. The model allows to investigate the influence on the behavior of the arc and on the evolution of the temperature inside the anode of an external magnetic field induced by a current flowing in an external conductor. If the currents of the arc and of the external conductor have opposite directions, the magnetic fields mutually repel and the arc is deflected. Such a practice to obtain a deflected arc finds applications in surface treatment of metallic substrates.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
