NON-CONTACT AND NON-DESTRUCTIVE TESTING METHOD AND DEVICE FOR ITS IMPLEMENTATION Russian patent published in 2018 - IPC G01N29/04 G01N27/82 

FIELD: fault detection.

SUBSTANCE: invention relates to the field of nondestructive testing during the magnetic and ultrasonic non-contact flaw detection methods implementation for the flaw detection and the geometric dimensions determination of products at significant scanning speeds. Summary of the invention is in that performing the controlled article magnetizing by means of magnetization unit, measuring the magnetic field parameters in the magnetic conductor interpole space near the controlled article surface and judging on the flaws presence by the measurements results, magnetization unit is made in the form of two-wheel carriage, created by the magnetization unit magnetic field, is additionally used for the non-contact excitation and ultrasonic oscillations reception realization by the electromagnetic-acoustic method, the method inductor is placed in the carriage wheel with the product contact spot zone, judging on the flaws presence and type by the ultrasonic and magnetic methods signals joint analysis results. To implement the method in the device, the magnetization unit is made in the form of a two-wheeled carriage, the carriage wheels are used as the magnetization unit poles, in the carriage wheel a groove is made along the wheel entire perimeter, in the wheel groove the electromagnetic-acoustic method inductor is arranged, electromagnetic-acoustic monitoring method inductor and the magnetic method sensor are connected by the device electronic unit.

EFFECT: expansion of functionality, increase in the products non-destructive testing reliability and accuracy.
