The paper presents the results of testing the tendency to intergranular corrosion of welded joints of dissimilar steels 12Kh18N10T and AISI 316 without heat treatment, as well as after quenching and stabilizing annealing. By welding control samples, optimal parameters of argon-arc welding were determined for pipes with a diameter of 42 mm and a wall thickness of 3.5 mm. A filler wire was selected according to Scheffler diagram.
