METHOD FOR DYNAMIC ADJUSTMENT OF THE SENSITIVITY OF FLAW DETECTION TOOLS DURING HIGH-SPEED TESTING OF LONG OBJECTS Russian patent published in 2022 - IPC G01N29/30 

FIELD: flaw detection tools sensitivity dynamic adjustment.

SUBSTANCE: invention is intended for dynamic adjustment of the sensitivity of flaw detection tools during high-speed testing of long objects. The substance of the invention lies in the fact that the relative movement of the flaw detection tool and the controlled object is carried out in a certain speed range, periodic emission of ultrasonic probing signals into the controlled object is performed, the signals reflected from the same structural elements of the object are received and recorded, their parameters are measured, by which the sensitivity is corrected flaw detection tool, at the same time, the current control speed is measured, a data set of signals from structural elements is preliminarily formed at different speeds and control sensitivities, on the basis of the data set, the relationship between the average signal parameters, sensitivity and control speed is established, when performing working control according to the parameters of signals measured at the current speed from structural elements calculate the required amount of correction of the sensitivity of the flaw detection tool.

EFFECT: improving the quality and reliability of testing long objects of control by dynamically adjusting the sensitivity of flaw detection tools in a wide range of scanning speeds.
