The influence of welding current and nitrogen content in argon shielding
gas on the resistance of the welded joint (weld metal and heat‐affected zone
[HAZ]) of the stainless steel X5CrNi18‐10 to the formation and growth of pits
was investigated. Also, the susceptibility of the welded joint to intergranular
corrosion was examined. Pitting corrosion resistance indicators were determined
based on anodic potentiodynamic polarization measurements in
NaCl + Na2SO4 solution, while susceptibility to intergranular corrosion was determined by the potentiokinetic method with a double loop
(DL EPR). SEM/EDS was used to analyze the microstructure. It has been
shown that higher nitrogen content in shielding gas leads to an increase in the
resistance of welded joints (weld metal and HAZ) to the pit formation.
However, an improvement in the resistance to the pit formation leads to a
decline in the resistance of the welded joint to pit growth. An explanation
of this phenomenon is proposed. ...Also, it was shown that the increase of
the welding current increases the susceptibility of the welded joint to
intergranular corrosion, while the higher nitrogen content has no effect.
