To the question of thermal joining of composite Al-B materials

Abstract

This work deals with the application of new approaches to welding production of modern light, strong, and heat-resistant metal composite materials in aeronautical and space technology. The objective of this article is to substantiate introduction of modern technology for welding composites in production, namely the development of argon-arc welding technology and the choice of equipment when using composites of the Al-B system for manufacturing the flame tube of the combustion chamber of an aircraft engine. Based on the study of technical literature and scientific publications, a short analysis of the existing technological processes for welding heat-resistant glass-ceramic composites was carried out. The problems arising in the process of welding aluminum composites reinforced with boron and steel fibers are considered. A modern gas tungsten arc welding based on new technological processes is offered with an example of welding in manufacturing a combustion chamber of a modern gas turbine modified engine.
