Influence of Aqueous Media on the Gas Saturation of Weld Metal in the Course of Underwater Welding of 12KH18N10T Steel.

We estimate the potentials of hydrogenation and oxidation of aqueous media, the degree of gas saturation of the weld metal, and the mechanical properties of a welded joint obtained as a result of wet underwater welding with an experimental self-shielding wire. We study the influence of aqueous media on the physicochemical and metallurgical processes in the course of underwater arc welding. We also develop a complex of metallurgical and technological measures aimed at guaranteeing the high quality of joints formed by this kind of welding of 12Kh18N10T corrosion-resistant austenitic steel.
