Abstract
New devices providing information on internal structure of a part and its defects are described. Acoustic-emission systems allow identification of such dangerous sources as plastic deformation, initiation and propagation of cracks and corrosion damages. Ultrasonic tomograph registers information on configuration, size and orientation of defects. Spectral-acoustic monitoring systems are suggested for measuring volumetric two-axial stresses. New solution to a practical problem of development of technology and equipment for NDT of austenitic welds in joints from 5 to 100 mm thick is described.
Keywords: welded structures, life of structures, non-destructive testing, diagnostics, acoustic-emission systems, spectral-acoustic systems, devices
