Innovative Technology of Mechanized Wet Underwater Welding of High-Alloy Corrosion Resistant Steel

Section: Scientific Basis of Innovation Activity
Language: Ukrainian
Abstract: The results of the practice of welding-repair technology using self-shielded flux-cored wire for wet underwater welding of high-alloy stainless steels type 18-10 are presented. The application of the technology allows reducing human participation in welding process under the extreme conditions. The practical value of the technology consists in the possibility of welding-repair works directly under water without any additional assembly works.
Keywords: wet underwater welding, steel 12Cr18Ni10Ti, NPS, self-shielding flux-cored wire, FCAW, covered electrodes.
