Acoustic Emission Testing (AET)
Acoustic Emission Testing (AET)

Acoustic emission testing is an NDT method that is based on the generation of waves produced by a sudden redistribution of stress in a material.

Electromagnetic Testing (ET)
Electromagnetic Testing (ET)

Eddy current is the most widely applied electromagnetic NDT technique. The eddy current method is also useful in sorting alloys and verifying heat treatment. Eddy current testing uses an electromagnet to induce an eddy current in a conductive sample.

Film Radiography (FR)
Film Radiography (FR)

Type of radiation used, whether x-rays from an x-ray generator or gamma rays from a radioactive source. Kilovoltages available with the x-ray equipment or the intensity of the gamma radiation. Relative importance of high radiographic detail or quick and economical results.

Infrared Testing (IR)
Infrared Testing (IR)

Infrared/Thermal Testing, or infrared thermography, is used to measure or map surface temperatures based on the infrared radiation given off by an object as heat flows through, to or from that object.

Laser Testing Methods (LM)
Laser Testing Methods (LM)

Laser Testing Methods (LM) Laser testing includes three techniques: Holography, Shearography and Profilometry. All three techniques use lasers to perform the inspections. Laser NDT methods based on interferometic imaging, primarily holography and shearography have seen growing acceptance since the mid 1980’s. With a large increase in the use of composite materials and sandwich structures ...

Leak Testing (LT)
Leak Testing (LT)

Leak testing methods What is NDT? Leak testing is also sometimes included in NDT and the methods used vary from simple bubble testing by visual examination, to very sensitive methods using radioactive gases.

Liquid Penetrant Testing (PT)
Liquid Penetrant Testing (PT)

Dye penetrant inspection (DPI), also called liquid penetrate inspection (LPI) or penetrant testing (PT), is a widely applied and low-cost inspection method used to locate surface-breaking defects in all non-porous materials (metals, plastics, or ceramics).

Magnetic Particle Testing (MT)
Magnetic Particle Testing (MT)

Magnetic Particle Inspection (MPI) also sometimes called as Magnetic Test (MT) is a non-destructive test method for the detection of surface and sub-surface discontinuities in ferrous materials. The test method involves application of magnetic field externally or applying electric current through the material which in turn produces magnetic flux in the material.

Radiographic Testing (RT)
Radiographic Testing (RT)

Radiographic Testing (RT or X-ray or Gamma ray) is a non-destructive testing (NDT) method that examines the volume of a specimen. Radiography (X-ray) uses X-rays and gamma-rays to produce a radiograph of a specimen, showing any changes in thickness, defects (internal and external), and assembly details to ensure optimum quality in your operation.

Ultrasonic Testing (UT)
Ultrasonic Testing (UT)

Basic Principles of Ultrasonic Testing Ultrasonic Testing (UT) uses high frequency sound energy to conduct examinations and make measurements. Ultrasonic inspection can be used for flaw detection/evaluation, dimensional measurements, material characterization, and more.
