Abstract
Welded joints on low-alloy steels of increased strength made underwater using electrodes with Cr-Ni alloy rods have been studied. The effect of the environment on gas saturation level and density of deposited metal, structure and properties of different zones in a welded joint has been evaluated. It is shown that the use of high-alloy electrodes makes it possible to increase ductility and strength of weld metal up to a level of those of the base metal
Keywords: underwater welding, coated electrodes, welded joint, chromium-nickel weld metal, structural constituents, gas saturation
