Nondestructive Testing Specialist – A Unique Career

If you are looking for an offbeat career option, you should consider the career of NDT technician i.e. non-destructive testing specialist. If you haven’t heard about this field, here’s a basic description and common techniques and methods used while performing NDT.

NDT programs are offered by Spartan College that includes NDT testing certification. Students can complete the NDT testing program in as little as 11 months and further finish their degree training in quality control management in extra 6 months. Spartan College also has HVAC programs as well as many other certificate programs.

What is Nondestructive Testing?

NDT is the process of testing, inspecting or evaluating components, materials or assemblies for differences or discontinuities in characteristics without damaging the functionality of the system or its part. Thus, when inspection is finished the system or part is still usable.

Unlike NDT, other tests are destructive in nature and so, are done only on a limited number of sample, instead of on the materials, assemblies or components that are actually put into service.

These damaging methods are usually used to find the physical properties of the materials, like ductility, tensile strength, impact resistance, yield, fatigue strength and fracture strength. However, differences and discontinuities in the material properties are found more effectively by NDT.

These days modern nondestructive tests are applied to fabrication, manufacturing and in-service inspection to confirm product reliability and integrity, to reduce production costs, control manufacturing processes and maintain a uniform quality level.

In the construction field, NDT is used to confirm the quality of materials and joining processes in the erection and fabrication phases and in-service NDT checking is used to make sure that the products used keep having the integrity required to confirm the usability and safety of the public.

You’ve to remember that while the medical industry makes use of several of the same processes, the term “nondestructive testing” is usually not used to explain medical applications.

Test Methods

The names of test methods often derive from the kind of penetrating medium or the device used to conduct the test. Various methods used today are:

  • Liquid Dye Penetrant
  • Ultrasonic Testing
  • Radiography
  • Neutron Radiography
  • Magnetic Particle Testing
  • Eddy Current Testing
  • Leak Testing
  • Microwave Testing
  • Laser Testing

All in all, the study of NDT is extremely interesting and you can pursue the career of NDT analyst because they are on a great demand in industries including construction, aviation, railroads, aerospace, manufacturing, alternative energy plants and amusement parks.

Thus, if you think that you’ve found a good career option, join a NDT course and develop a unique career.
