In the last few years, electromagnetic acoustic transducer (EMAT) has come to prominence for its ability to quickly scan exposed pipelines for corrosion, cracks, and other defects using medium-range guided waves and without the requirement for liquid couplants.
While they is very efficient and popular, liquid couplants used for ultrasonic inspection have some inherent limitations and disadvantages. An alternative method to using liquid couplant is Dry-Coupled Ultrasonic Testing (DCUT).
Readers were previously introduced to some of the practical advantages of EMAT Ultrasonic Testing (UT) in the March/April 2013 and July/August 2013 issues of Inspectioneering Journal. In this article, I will cover the practical advantages of EMAT for in-service applications using Medium Range Ultrasonic Testing (MRUT).
Non-contact ultrasonic testing with EMAT was formally introduced in part one of this series found in the March/April issue of Inspectioneering Journal. Readers were introduced to the practical advantages of EMAT Ultrasonic Testing.
This is the first in a series of three articles that will introduce Electro Magnetic Acoustic Transducer (EMAT) and its practical applications in the field of nondestructive testing (NDT). EMAT, or Electro Magnetic Acoustic Transducer, is an Ultrasonic Testing (UT) technique that generates the sound in the part inspected instead of the transducer.
