NDT Services

Nondestructive testing (NDT) is the process of inspecting, testing, or evaluating materials, components or assemblies for discontinuities, or differences in characteristics without destroying the serviceability of the part or system. In other words, when the inspection or test is completed the part can still be used

NDT is an acronym that stands for Nondestructive Testing. 

NDT is a field of engineering encompassing the testing and inspection of materials and equipment to evaluate condition, find flaws and defects, and extend the useful life of the infrastructure all around us. 

Sometimes broadly termed 'industrial inspection', NDT is the interdisciplinary engineering field dedicated to ensuring the structural components, systems, and infrastructure used in construction and industry stay in a reliable and safe state. Besides ensuring the cost-effective operation of mills, factories, airplanes, and municipal systems, NDT also ensures the safety of all persons in and around these systems. 

The key difference between NDT and other forms of materials evaluation is that NDT allows in-situ evaluation or inspection of the part without modifying or permanently damaging the part. Many of the technologies developed for medical imaging are used in NDT, in addition to many other high-energy forms of inspection, unique to NDT, that would be harmful if used on living tissue. 

The term NDE (Nondestructive Evaluation) is sometimes used to describe NDT methods that result in quantitative measurements of material characterization, for instance the size of an indication, a measure of remaining life of a part, or another quantitative characteristic of a material or part. 

The six most frequently used test methods are MT, PT, RT, UT, ET and VT. Each of these test methods will be described here, followed by the other, less often used test methods.

Ultrasonic Testing (UT)
Ultrasonic Testing (UT)

Ultrasonic testing uses high-frequency sound energy to perform examinations and make measurements.

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

Magnetic particle testing is a relatively simple test method that can be applied to ferromagnetic materials including finished articles, billets, hot rolled bars, castings and forgings.
