Abstract


Obtaining permanent joints of the required quality of dissimilar materials is essential for the development of rocketry. We have made a series of experiments designed to produce welds providing stable mechanical properties and microstructure of the samples studied, which are selected on the basis of optimal welding parameters. Carried microstructural studies of the samples obtained using various welding parameters, showed that the samples of the selected parameters are not in mesh intermetallic weld zone.


Keywords
