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 a_melt both of ferromagnetic and nonmagnetic materials. Maximum increase of wire a_melt is 20-30 % at the magnitude of transverse component of TMF induction of 30-45 mT.
