UEC-Saturn (part of the United Engine Corporation of Rostec) was the first among UEC enterprises to introduce rotational welding for the serial production of gas turbine engine components. The new technology guarantees excellent quality of welded parts and significantly reduces the time spent on the operation.
Previously, electron beam welding was used in the manufacture of rotors at the enterprise. The use of the friction rotational welding method ensures 100% acceptable parts for the welded joint and reduces the welding operation time by 10 times.
The UEC press service emphasized that friction rotational welding is one of the key technologies in the modern aircraft engine industry. This method allows joining various materials, including those that are not amenable to traditional fusion welding.
The formation of a welded joint occurs due to rapid heating and compression of parts. The temperature increases in a thin surface layer as a result of friction, where one element rotates and the other remains static.
Earlier www1.ru reported that to increase the production rate of MS-21 aircraft at the Irkutsk Aviation Plant installation of four new machines has begun.
