Modern construction is unthinkable without gas welding. Gases used for this purpose are described in the sections "Metallurgy" and "Mechanical Engineering".
- Welding in a deepwater environment (submarine tunnels, pipelines, buried part of above-ground structures, etc.) - hydrowelding - requires dry stable environment. Inert gases help to eject water from the waterbox, they are usually fed there under high pressure. In addition, technical gases are used for the first welding itself.
PSKOVTEHGAZ® develops, manufactures, repairs, maintains and modernizes the related equipment: pump units, evaporators, gasifiers, tanks, ramps, etc., and also provides various services and implements integrated engineering projects.
