The United Engine Corporation (UEC, part of the Rostec State Corporation) uses rotary welding in the production of aircraft engines. This was reported by the company's press service.
UEC noted that the principle of the method is very simple: one part rotates very quickly, and the other is pressed tightly against it, and then physics comes into play.
Due to friction at the junction of the parts, a high temperature arises, which melts the metal.
As a result, two parts are seemingly "rubbed" into each other, and a very strong connection is formed. Thanks to this technology, welding time can be reduced by 10 times. The seams are strong, and the number of defects is zero.
The corporation added that rotary welding allows joining materials that are "unweldable" by traditional methods, which is important for the production of modern aircraft engines.
It is worth mentioning that UEC enterprises are currently producing PD-8 and PD-14 aircraft engines for promising passenger import-substituted MC-21 and SJ-100 aircraft.
Earlier www1.ru reported that small aviation in Russia will receive a powerful impetus from Rostec and UAC.
