Abstract

Results of studies of nondestructive control of multilayer titanium panel, made by the method of diffusion welding and superplastic forming, are considered. By ultrasonic control of the echo method with the use of a direct piezoelectric transducer, areas on which diffusion did not occur or has not occurred completely, as well as various inclusions trapped in the welded joint area during assembly, are determined. The quality of the formation of the inner surface (corrugated sheet) can be controlled by radiographic inspection, and according to the results of the control, it is possible to detect breaks, cracks, and the violation of the shape of internal partitions that appear from a technological process failure.
