What is non-destructive testing?

Many people want to know what non-destructive testing is. This is the process of evaluating, testing and inspecting materials for differences in properties without destroying the system. When we use NDT, the parts can still be used afterwards and function perfectly well. Read on for a deeper discussion of non-destructive testing and the most popular test methods used when performing NDT.

Benefits of NDT

While other types of tests can be destructive and are therefore limited to being performed only on a few select samples, in NDT the materials, components and parts can be placed into active service following the test because they are in good working order.

Destructive tests can sometimes be used to find out physical strength, resistance, ductility, yield and other properties of materials. However, for discovering the differences and discontinuities in materials, it is usually more useful to use non-destructive testing techniques.

When are non-destructive tests used?

Non-destructive tests are often used in the manufacturing industry to assess product reliability. These tests can control manufacturing processes and reduce the costs of production while maintaining a standard acceptable level of quality. NDT is used during the construction phase to ensure materials are reliable, efficient and safe.

NDT test methods

Test methods refer to the type of equipment used to perform the test. Some popular NDT methods include Radiographic Testing (RT), Visual Testing (VT), Laser Testing Methods (LM), Magnetic Particle Testing (MT), Electromagnetic Testing (ET), Ultrasonic Testing (UT), Liquid Penetrant Testing (PT), Thermal/Infrared Testing (IR), Acoustic Emission Testing (AE) and many more testing methods for different properties of materials.

Surface engineering specialists

NDT testing is performed by surface engineering specialists from companies such as https://www.poeton.co.uk/ and other specialists. These types of companies can provide surface treatments and coatings of all different types and materials, including bespoke solutions and advanced technologies. This article created in collaboration with the Iowa State University explains further about NDT.

Types of surface

The types of surface offered from these companies include paint, plating, thermal spray and anodising techniques. These surfacing options require testing and NDT is the ideal way to test these materials to ensure they have the correct reliability, efficacy and safety for the task. Once customers have decided on the type of surface they want, engineers can prepare the surface and the NDT tests performed ensure premium efficiency of the surface solution.
