New Tendencies in Development of Carbonaceous Additives for Welding Fluxes

[摘要] The paper provides results of comparative analysis of the effect of carbonaceous components introduced into welding fluxes on molten metal - slag interaction. Thermodynamical calculations of dehydrogenization are presented for submerged arc welding. A positive influence of carbonaceous additives on gas content and mechanical properties of welds is demonstrated. Carbon and fluorine containing additives are emphasized to be promising for automatic submerged arc welding.
