Nondestructive Testing - NDT Lab

Rely on our NADCAP-accredited nondestructive testing to analyze your materials for cracks, weld verification, voids and other defects.

Liquid Penetrant Inspection

Liquid Penetrant Inspection

Liquid penetrant inspection is a valuable tool in checking for material flaws in welds, castings, and other components that cannot be destroyed and also for determining other characteristics such as surface porosity.

Magnetic Particle Inspection

Magnetic particle inspection (MPI), also know as Magnaflux, is a highly-sensitive nondestructive test (NDT) that identifies defects on the surface and shallow subsurface of ferromagnetic materials such as iron, nickel, cobalt and some of their alloys.

Frequently Asked Questions

What is Nondestructive Testing?

Nondestructive testing (NDT), also known as nondestructive examination (NDE), is an analysis technique that examines materials, components, or structures without causing damage to the original part. Unlike other destructive testing methods, the part that was examined can continue to be used after nondestructive testing.

What are Nondestructive Examination Methods?

There are many test methods associated with nondestructive testing. Commonly, NDT test method names refer to the method of penetration or equipment that is used for the test. Sub Source specializes in Liquid Penetrant Inspection (LPI), Magnetic Particle Inspection (MPI), and Nital Etch (also known as Temper Etch).

What are the Advantages of NDT?

Nondestructive examination methods have a few distinct advantages. Most importantly, the non destructive nature of the testing means that equipment can continue to be used and/or repaired if any issues are found. This makes NDT more cost efficient than destructive testing methods. Additionally, many nondestructive testing methods are harmless to humans, making them safe to perform.

What is the difference between NDT and NDE?

Oftentimes, the terms NDT (nondestructive testing) and NDE (nondestructive examination/evaluation) are used interchangeably. Technically speaking, NDE is used to describe quantitative measurements. Not only can NDE identify a defect, but it can also provide information such as its size or shape.

What is Magnetic Particle Inspection?

Magnetic Particle Inspection (MPI), also known as Magnetic Particle Testing (MPT), is a nondestructive testing method to identify surface and near-surface issues in ferromagnetic materials. Magnetic Particle Inspection is commonly used to identify cracks. MPI is a popular NDE method due to its low-cost and relative ease.
