摘要

The article represents the results of researches of EMA transduction in pulse magnetic field. Along with were developed the means and equipment for EMAT excitation by pulse sequence, corresponding to Barker code. Given the features of structure and parameters of EMAT, technical characteristics and examples of application for the developed A1271 device for thickness measurements of tube walls with corrosion and erosion defects.
