ABSTRACT. Is carried out the thermodynamic estimation of the probability of the flow of the processes of the removal of hydrogen from the weld with the welding in the fluorine-bearing flux in the standard states in the range of temperatures 1700  –  2200 k. In this case, as the standard states for the substances – of reagents they were selected: Na3AlF6L, SiO2L, SiF4g, NaAlO2s, Na2SiO3l, CaF2l,  CaSiO3l, H2g, SiF2g, HFg, O2g, SiFg, Hg. As a result the calculations of standard energy of Gibbs and equilibrium constants of reactions it is determined, that from the reactions of the direct interaction of ftoragentov of slag with hydrogen and oxygen of the metal most probable appears the reaction with the cryolite. In the mechanism of more complex interaction with the participation in the reaction, besides ftoragentov, silica of slag and by the possible formation of the intermediate product of SiF4g more probable is the process with fluorite. Calculations showed the expediency of using the connection Na3AlF6 together with fluorite for the removal of hydrogen with the submerged welding. The carried out calculations became the basis of the development of the compositions of the new flux- additives, protected by patents RF.
