ULTRASONIC CONTROL METHOD OF OBJECTS WITH SHAPE OF BODY OF ROTATION Russian patent published in 2008 - IPC G01N29/04 

FIELD: physics; measurements.

SUBSTANCE: technique lies in that, in the manual mode, the sensitivity of flaw-detection equipment is tuned, the controlled object is installed on a stand, the object is centralised, the converter is brought into the zone of initiating control on the surface of the object, and the automatic control mode is switched on. Using the converter, the surface of the object is scanned in spiral form and presence or absence of defects on the object is fixed during the control process by the flaw-detection equipment. After manual tuning of the flaw-detection equipment, it is then checked in automatic mode and input-receiving of acoustic oscillations in the object during its control, as well as in reference during tuning and its checking is achieved through the contact-slot method with use of a converter with a local basin.

EFFECT: increased efficiency of controlling the objects with the shape of body of rotation, smaller dimensions and amount of metal in the measuring unit.
