Abstract
The paper gives the results of thermodynamic calculations of probable metallurgical reactions in submerged-arc welding using agglomerated fluxes, which promote lowering of partial pressure of hydrogen within the arcing zone and suppressing the diffusivity of hydrogen in the weld. They are in good agreement with experimental data. It is concluded that the use of fused intermediate products is advantageous for production of welding fluxes, in order to decrease the hydrogen content of weld metal.
Keywords: arc welding, low-alloyed steel, welded joints, hydrogen in welds, flux, metallurgical processes
