Abstract
At present, a wide variety of designs for electromagnetic-acoustic transducers (EMAT s) are known, which are intended for measurements, quality control, and diagnostics of materials and products. Such transducers generate and receive pulses of all known ultrasonic wave types in metal products, both ferromagnetic and non-ferromagnetic. Recently, there has been intensive development of transducers that use powerful pulsed magnetic fields. On one hand, these are structurally more complex under the same conditions, but on the other hand, they offer a significant advantage when measuring characteristics of ferromagnetic objects, since they practically eliminate mutual attraction forces. The complexity of EMAT designs with pulsed magnetization necessitates research into optimal parameters and the application of new operating methods, considering the simultaneous interaction of dynamic magnetic and high-frequency electromagnetic fields in the surface layer of the metal product — during both the excitation and reception of ultrasonic wave pulses. It is especially important to account for such interaction in widely used measuring combined ultrasonic straight EMAT s with pulsed magnetization. Therefore, it is advisable to conduct mandatory experimental studies to determine the optimal parameters, as the available theoretical works do not provide sufficiently accurate results needed for the development of technologies and the design of new measurement and control tools operating with pulsed magnetization.
Keywords: experimental research, ferromagnetic product, ultrasonic pulses, electromagnetic-acoustic, measurement, control, diagnostics, magnetic field, electromagnetic field, pulsed magnetization
