Main Developments of the E.O. Paton Electric Welding Institute in the Field of Non-Destructive Testing

摘要

The E.O. Paton Electric Welding Institute of the NAS of Ukraine is a world-known technological complex in the filed of welding and related technologies, one of which is non-destructive testing. Described are the most famous developments of the Institute in the field of non-destructive testing, being performed together with other companies and implemented in different countries, namely X-ray television system based on CCD matrix and luminescent screens; technology of tangential radiography and radioscopy; pilot model of ultrasonic system for testing of extended objects without scanning of their surface using low-frequency ultrasonic waves; systems of automated control using piezo- and EMA-excitation of ultrasonic waves for detection of pipe defects; procedures for evaluation of dimensions of internal crack-like defects based on TOFD, SAFT, phased-array method; movable magnetizing devices on constant magnets; system of magneto-optical testing for detection of thin defects without intermediate carriers of information about magnetic leakage fields etc.
