"ODK-Saturn" (part of PJSC "United Engine Corporation" of Rostec), was the first among UEC enterprises to introduce rotary 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 rotary welding method ensures 100% suitable parts for the welded joint and reduces the welding operation time by 10 times.
The press service of UEC emphasized that friction rotary 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 in order to increase the production rate of MS-21 aircraft at the Irkutsk Aviation Plant installation of four new machines has begun.
