Abstract
The work deals with the results of investigations of influence of pulsed electrode wire feed parameters on the conditions of deposited metal bead formation, wear resistance and losses of electrode metal in electric arc surfacing in CO2. The comparative analysis of results was carried out obtained at constant and pulsed electrode wire feed. It was shown that change in electrode wire feed rate at constant power parameters of surfacing process allows efficiently influencing the formation of deposited bead, wear resistance and amount of losses of electrode metal. The given result is achieved due to change of kinematical conditions of electrode metal transfer from the electrode end through the arc gap to the molten metal pool. 11 Ref., 4 Figures.
Keywords: deposited metal, electrode wire pulsed feed parameters, geometric parameters of deposited bead, electrode wire feed rate, losses of electrode metal, control of electrode metal transfer
