Improvement of Flaw-Detecting Apparatuses for Magnetic Quality Control of Tubular Products

摘要

Possible ways of improving the magnetic nondestructive testing (NDT) method are outlined. They are based on the use of computer technologies, thin-film matrix transducers, and approximate solution methods of the inverse problem of magnetic flaw detection, which allow the geometry of flaws to be reconstructed on the basis of stray fields measured in real time. We determine principal lines in the field of designing flaw-detecting instrumentation intended to computerize the quality control of tubular goods and guaranteeing the realization of advanced NDT methods and required service level.
