Abstract
This article contains the main technical information on the measuring system and the eddy-current transducer used, and describes the measurement procedure to control defects in welds of titanium alloys, including the use of two subminiature eddy-current transducers, one of which is to be fixed above the weld, and the 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. Dependences of the eddy-current transducer signal that show the changes of the weak and defect-free weld signals are given. Defects in welds are defined by a dramatic drop in signal amplitude of the eddy-current transducer signal when scanning weld areas with defects. Experiments were conducted on welded BT1-0 titanium plates. The article contains the results of these measurements. The dependence data facilitates the assessment of the quality of welding seams and helps make an educated conclusion about welding quality.
