The influence of amplitude and frequency of oscillations of electrode wire during arc surfacing on formation of deposited
beads, nature of base metal penetration, as well as structural and chemical heterogeneity in the zone of the
joint of deposited and base metals were studied. It was established that an increase in the frequency of oscillations of
electrode wire, at the same amplitude of oscillations and rate of deposition, leads to an improvement in formation of the
deposited metal and mixing of the layers in the deposited metal; formation of a more dispersed structure; narrowing of
the transition zone; more uniform distribution of alloying elements; more uniform penetration and «smoothing» of the
fusion boundary of the deposited and base metal. The mentioned regularities almost do not change with an increase in
the amplitude of oscillations. It was established that the best formation of the deposited metal occurs at the maximum
frequency N = 45 min‒1 and amplitude of oscillations of the electrode wire A = 25 mm and deposition rate Vd = 7 m/h.
