Measuring system for studying quality of welded joints of titanium plates by using subminiature eddy current transducers

This article contains the main technical information on the eddy-current transducer (ECT) used. This article describes the measurement procedure to control welds of titanium alloys, including the use of two supermimiature ECT, one of which is to be fixed above the weld, and another is to be used directly for scanning. The experimental results obtained by means of the developed measuring system for samples of various titanium plates joined by welds are presented. Likewise, a poor-quality weld can also be detected by a dramatic drop in amplitude of the signal when scanning the weld / welded material. The article presents the results of studies of titanium samples joined by a faulty weld, samples joined by a completely faulty weld, and also samples joined by a defect-free weld. The obtained dependences make it possible to determine the quality of the weld by the signal of an eddy-current transducer and to draw a conclusion about the reliability of welding.
