Abstract
The effect of surfacing conditions, compositions of charges of flux-cored wires and fluxes on the formation of a horizontal bead on inclined and vertical surfaces is experimentally investigated. It is shown that deposition on such surfaces should be done at a minimum possible amperage and maximum speed. The best choice for surfacing is the short flux of the AN-15M grade. The CaCO3-CaF2-TiO2 gas-slag forming system with a component ratio of 3:1:1 provides the best results in the manufacture of self-shielded flux-cored wire.
Keywords: surfacing, inclined surface, bead, molten pool fluidity, surface tension, bead cross section asymmetry
