ОСК внедряет лазерные и аддитивные технологии на предприятии Севмаш в Северодвинске

In Severodvinsk, Arkhangelsk region, on September 2, 2025, a meeting was held at the USC Sevmash enterprise dedicated to the development of laser welding and additive technologies in shipbuilding. Representatives of the enterprise and specialists from St. Petersburg Polytechnic University took part in the discussion.

The meeting identified areas for the introduction of modern technologies into production. For the first time at Sevmash, it is planned to use laser welding and additive technologies for the manufacture of large thickness products. Laser welding allows making joints in one pass without edge preparation, with high speed and quality, without the use of expensive materials, such as fluxes or filler wire, said Anatoly Abramov, chief welder of the enterprise.

To implement the project, Sevmash and St. Petersburg Polytechnic University will soon sign an agreement on joint research. The goal is to develop a welding technology for samples with a thickness of at least 30 mm with the necessary mechanical properties. Data on the timing of the introduction of technologies and their impact on production are still being clarified.

The USC Sevmash enterprise, located in Severodvinsk, is one of the largest shipbuilding plants in Russia, specializing in the construction of nuclear submarines and other large ships.
