Abstract
The results of modelling the processes of carbide formation in the metal of welded joints in 12Cr18Ni10Ti high-alloy steel, produced by manual arc welding with electrodes with different types of coatings – rutile (OK 61.30) and basic (TsL-11) – are presented. Intercrystalline corrosion can be suppressed by initiating the bonding of carbon in carbides by titanium and niobium transferred into the welded joint from the coating.
