Abstract
The effect of double-jet gas shielding on the quality of welded joints on low-alloy shipbuilding steel in multilayer arc welding in gas mixture shielding atmosphere is considered. The possibility of reducing chemical and structural heterogeneities in the joints and improving their mechanical properties is noted.
