The effect of oscillating movement amplitude and frequency of electrode wire swinging on forming of pad weld runs, the character of parent metal penetration, as well as structural and chemical inhomogeneityin the zone of intermixing padding weld with parent material has beentested while submerged arc surfacing using oscillating electrode. It has been stated that along with increasing frequency of electrode wire end oscillations and the same amplitude and surfacing speed, the weld runformation is improved, the width of the zone of padding weld intermixture with parent material is reduced and more dispersive structure with lower structural and chemical inhomogeneity in a padding weld is be- ing formed. More uniform fusion penetration into the parent material and alignment of fusion line can be observed. Those relations remain practically unchanged with increasing amplitude of oscillation.

The electrode wire melting coefficient (αm) is determined for the submerged arc surfacing and welding in a longitudinal magnetic field (LMF) under reverse and direct polarities with ferromagnetic and paramagnetic (non-magnetic) wires. The maximum gain in the wire melting coefficient is achieved in the magnetostatic field assisted surfacing and welding. The effect reduces with the LMF frequency increasing to 4-6 Hz and virtually does not change with the further increase to 50 Hz. The electrode wire melting coefficient is shown to increase depending on magnetic properties.It has been established that the penetration depth of the parent metal reduces at the 50 Hz LMF surfacing when the longitudinal induction exceeds 65 mT.The constant and alternating LMFs reduce the speed of in-bath liquid metal flows, which results in the reduced parent metal penetration efficiency at surfacing.
