austenitic steels; welding fluxes; technological strength; δ-ferrite; hot cracking; intergranular corrosion; submerged arc welding; weld metal phase composition; slag basicityAbstract
The study examines the effect of different welding fluxes on the technological strength, phase composition, and
corrosion resistance of weld metal in automatic welding of steels 0Х18Н10Т, 0Х18Н12ТФ, and 0Х20Н12АБФ up to 120
mm thick. It was established that increased slag acidity and oxidizing ability promote oxidation of alloying elements and
reduce δ-ferrite content, decreasing resistance to hot cracking. The most stable results were achieved with flux 48-ОФ-6.
Its application ensures optimal phase balance and high corrosion resistance of welded joints. The findings can be used in
selecting welding consumables for critical structures operating in aggressive environments.
