New Applications of Electromagnetic Techniques in NDT Inspections

摘要

The requirements relating to the performance and scope of industrial plant component inspections have evolved considerably due to the need to increase the reliability and availability of such installations. There are currently two ways to increase the reliability and field of application of inspections: one consists of using various traditional techniques in a complementary manner, and the other of using new techniques. At this respect, the appearance of new inspection technologies based on electromagnetic principles will allow the inspections currently performed to be complemented and improved. These electromagnetic techniques involve two aspects of interest: on the one hand, the movement of the sensor across the area of interest is simplified since it is not necessary to use any coupling medium between the two, and on the other higher scanning speeds are achieved.
