Nondestructive Testing’s Biggest Advantages and Disadvantages
Digital technology has greatly enhanced the convenience and accuracy to NDT processes, particularly in the areas of eddy current (EC) and ultrasonic (UT) techniques.
Eddy current is rapidly replacing liquid penetrant and magnetic particle testing as the preferred method in certain surface inspection applications.
Ultrasound technology using advanced techniques like phased array and time of flight diffraction (TOFD) greatly improve inspectors’ ability to identify volumetric flaws or defects.
