INCREASING INFORMATION DENSITY OF ULTRASONIC TESTING OF PLATES WITH THE USE OF THE EMAT

摘要

The report considers theoretical and practical aspects of increasing information density of ultrasonic testing of plates with the use of the EMAT. It gives principles of construction of multi-channel systems for detection of internal and surface defects and mechanical properties homogeneity estimation in a wide range of temperatures: from -40 to + 650 degrees Celsius.
