Abstract
Mathematical model of the process of removal of a drop from electrode tip in arc surfacing using the longitudinal magnetic field was developed. It is shown that a field pulse of the appropriate duration is required to remove the drop from the electrode tip at a certain value of the radial component of induction in the drop zone.
