EFFICIENCY OF MELTING OF ELECTRODE WIRE IN SUBMERGED-ARC SURFACING WITH INFLUENCE OF TRANSVERSE MAGNETIC FIELD

摘要

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