Abstract
The work considered the influence of the main parameters of the arc surfacing in protective gases with electrode transverse oscillations on the formation of low-carbon low-alloy deposited metal. It has been defined that the range of deposited beads defect-free formation modes is quite narrow and exists in the region of high values of welding current, low values of welding rate and electrode oscillation frequency. It is shown that the heat input increase of surfacing with the constant amplitude and frequency of oscillations allows not only to improve the formation of the weld bead, but also to obtain the smoother gradient of changes properties along the height of the multilayer deposited metal and at the heat-affected zone of the base metal.
