Ultrasonic thickness testing (UTT) is a nondestructive testing (NDT) method that assesses the thickness of metals and almost any other solid materials to see if they are wearing down and need to be fixed or replaced. Essentially, we can figure out the thickness of a...

Eddy current testing (ET) is a common method of electromagnetic testing used in nondestructive testing (NDT). Before we get into the details of this type of testing, let's start with the basics! An eddy is the flowing, circular current of elements like water, smoke,...

Visual testing is the oldest and perhaps most common type of nondestructive testing. It's exactly what it sounds like, inspecting a surface visually to ensure that the surface has no visible breaks or discontinuities. This isn't to say that visual testing is easy or...

Ultrasonic or ultrasound testing (UT) is a versatile inspection technique. It is used to test a variety of both metallic and nonmetallic products such as welds, forgings, castings, sheet, tubing, plastics and ceramics. This NDT method is often used instead of...

Magnetic Particle Testing (MT) is also known as MPI Magnetic Particle Inspection, yoke check, magnetism check, Magnaflux (which is actually a brand name of a popular Magnetic Particle and Liquid Penetrant chemical). Magnetic particle testing is used to test welds,...

Leaks can develop in all kinds of pipelines and other industrial systems. In order for these systems to function properly, leaks need to be identified and fixed. However, leaks may be hard to detect. This is where leak testing comes in. A professional nondestructive...

Liquid penetrant testing is known by a variety of other names: dye penetrant, fluorescent penetrant inspection (FPI),  red dye, fluorescent check, and blacklight check. It is also known sometimes known as Magnaflux check, however, Magnaflux is a name brand known for...
