Abstract

In this paper we will present our results related to the impact of activating fluxes in shielded arc welding with consumable or non-consumable electrode to the process productivity, intensity of the energy necessary for welding and the quality of welding joints. Thanks to the application of activating fluxes, during the use of non-consumable electrode, the penetration capability of electric arc is increased by 2 to 3 times, and during the use of consumable electrode 1,8 to 4 times, with simultaneous decrease of the intensity of the necessary welding energy by 2 to 5 times. At the same time, the productivity of a welding process and quality of welding joints increases. These positive effects of the welding process are conditioned by an increase in thermal coefficient of arc penetration and total heat coefficient of arc penetration.
