It is shown that in submerged-arc surfacing with the effect of constant transverse magnetic field the coefficient of melting of electrode wires of 3–5 mm diameter is increased by 25–30 %. It is experimentally found that at the effect of an alternating field at unchanged level of a transverse component of induction, the effect of increase in the coefficient of melting depends on frequency of this field. With increase of the field frequency up to 10–20 Hz, the increment of the coefficient of melting decreases to zero values. A procedure was developed for determination of the minimum level of transverse component of field induction in the electrode drop zone, at which the drop is detached from a melting electrode end. It is shown that the effect of decreasing the coefficient of melting at increase in the field frequency is predetermined by the reduction in duration of pulses. The paper gives the calculated data, allowing determination of optimum values of induction and frequency of the alternating field, at which the coefficient of wire melting at submerged-arc surfacing (welding) is increased. 8 Ref., 4 Figures.
