Abstract
Causes of increase in the efficiency of the process of electrode melting in submerged-arc surfacing at a reverse-polarity current in the longitudinal magnetic field (LMF) were examined. It is shown that the effect of increase in the coefficient of melting of electrode wire depends upon its magnetic properties, and shows up not only in the case of permanent LMF, but also in the case of the alternating one with a frequency of 50 Hz.
Keywords: arc surfacing, longitudinal magnetic field, electrode metal droplet, electrode melting coefficient, magnetic properties, ferromagnetics
