In this weeks article, Critical non-destructive testing applications: Part one of two, Michael Rakos, district manager of Magnetic Analysis Corporation talks about non-destructive testing (NDT), which was first developed in the late 1800s. Since then, a variety of technologies have been developed, including Eddy Current Testing (ECT), and Ultrasonic Testing (UT). These two methods often complement one another when used together.
ECT is primarily a surface test with attenuating subsurface flaw detection capability, while UT has the advantage of detection capability deep within materials, Rakos explains. As NDT techniques have expanded, so have the application which now encompass many critical products that are being used where it is extremely difficult and expensive to replace or repair, or where failure can cause serious and life-threatening consequences. What follows are some specific testing situations that illustrate the use of NDT for ensuring the safety and quality of these products.
