Popis: Theoretical bases and the results of experimental studies and practical application of ultrasonic monitoring (USM) are considered for butt and corner welded joints and equipment made of corrosion-resistant steels of the austenitic and austenitic-ferritic classes with a wall thickness of 4–30 mm. It is shown that the reliability of detecting impermissible weld defects relates to the requirements of specifications. USM entirely replaces radiographic monitoring.
