Abstract
The paper analyzes the state-of-the-art of underwater welding and cutting in Ukraine. It is established that coated-elec- trode wet welding now is the main process of underwater welding. In Ukraine practically all the metal structures are cut underwater by applying tubular-electrode oxy-electric cutting. Other underwater cutting processes have not been used lately.
Keywords: wet underwater welding, flux-cored wire cutting, oxy-electric cutting, coated electrodes, flux-cored wire, exothermal electrodes
