Electrical characteristics of the equipment for the hybrid plasma-MIG welding

In order to formulate requirements for electrical equipment for a prospective hybrid welding process Plasma-MIG, the following studies were carried out. The theoretical analysis of the influence of the plasma discharge temperature with non-consumable electrode on the melting of the electrode wire was carried out. The dynamics of the melting of the electrode wire and dynamics of circuit with consumable electrode arc were been investigation. The estimation of maximum values of the temperature of plasma have been made. Influence of the MIG process on the volt-ampere characteristics of the plasma discharge have been studied. These results were used for carrying out the technological experiments.
