Abstract
The development and application of automatic electric arc surfacing under flux with controlled periodic change of modes makes it possible to expand significantly the possibilities of traditional technological processes of surfacing. The carried out experimental investigations make enabled us to determine the advantages of the welding process with modulation of modes in comparison with welding in stationary mode. It is established that the parameters of the modulated welding current (frequency, sparseness) determine the degree of influence on the physical and mechanical characteristics of the welded metal and in most cases improve them compared to the characteristics of stationary mode. The result of the analysis defines that in the pulse mode it is possible to achieve the reduction of inclusions from the composition of the flux by almost 30%. This reduction is an additional factor in ensuring the characteristics of strength (hardness, wear resistance) of the weld roller and weld.
