Abstract

The article presents the results of research carried out in the development of technology for soldering pipelines of small diameter of aluminum alloys and dissimilar materials. The advantages of the alternative design of the collector of the heat exchanger of the spacecraft with brazed joints in comparison with bimetallic adapters and ring argon arc seams are shown. A comprehensive assessment of the proposed soldered compounds in terms of strength tests and leak tests, metallography and radiography is given.
