The Zheleznogorsk enterprise has introduced its own technology for manufacturing flexible waveguide sections (FWS) from copper alloy using blanks obtained by pulsed laser welding. According to the press service of "RESHEТNEV", the use of technology ensures high strength of the welded joint: metallographic tests and tensile tests showed at least 90% of the strength of the base metal, and the absence of welding defects.
The use of new technology provides the required geometric parameters of waveguide channels, and therefore, the accuracy of the passing signal. It also significantly reduces the time and cost of manufacturing products. Thus, Reshetnev company managed to reduce the production process of FWS blanks from multi-day cycles to three operations, which take a total of no more than four hours. At the same time, the operational characteristics of the products remain at the level of the best world analogues, which increases the competitive advantages of the waveguide products of the Zheleznogorsk satellite construction enterprise
Earlier in April, Reshetnev company announced that they are switching to their own localized production of waveguides, which serve for the passage of radio signals on board the satellite. Each waveguide consists of a metal tube and a flange, a metal flat disk at the ends of this tube, through which it is fastened to other tubes.
One spacecraft can have several hundred waveguides installed, which are connected to each other and form extended and curved waveguide paths. The better the waveguides, the safer the radio signal on board the spacecraft and the better the services for users.
