Gas chromatography method was used to study thermal desorption of hydrogen from mineral raw materials, used in manufacture of agglomerated welding fluxes. The good prospects for application of fused materials in the charge composition in agglomerated flux manufacture were established. Increase of fused material content in the composition of agglomerated flux charge leads to lowering of the flux susceptibility to sorption of environmental moisture. At increase of the content of fused material in the agglomerated flux charge from 15 up to 40% the diffusible hydrogen content in the deposited metal decreases from 3.5 to 2.6 cm3/100 g in submerged-arc welding with these fluxes. 12 Ref., 2 Tabl., 3 Fig.
Keywords: hydrogen, automatic arc welding with agglomerated fluxes, low-alloy steels
