Abstract
A device has been developed, which generates a transverse magnetic field (TMF), for the process of submerged-arc surfacing using wire. It is shown that in reverse polarity surfacing the impact of a constant and alternating TMF of 50 Hz frequency increases equally the coefficient of melting of electrode wire amelt both of ferromagnetic and nonmagnetic materials. Maximum increase of wire amelt is 20-30 % at the magnitude of transverse component of TMF induction of 30-45 mT.
