What Is Non-destructive Testing?
The name says it all – it’s a variety of testing methods that are non-destructive to the part or component being tested. Non-destructive testing allows you to test, inspect and evaluate components for discontinuities without destroying the serviceability of the part. In other words, when the test is complete, the part can still be used as intended. It’s also referred to as NDT.
What makes non-destructive testing better than other testing methods?
In contrast to NDT, other tests are more destructive in nature and are typically performed on a small sample rather than the entire assembly. While these methods are handy for determining physical properties of a material, this approach typically results in limited accuracy compared to NDT.
Who should use non-destructive testing?
It’s believed that the Romans used the concept of non-destructive testing, but the first recorded form of NDT dates back to 1868 when an Englishman used the magnetic properties of a compass to find cracks in the barrels of guns – other forms quickly evolved.
Today, modern forms of non-destructive testing are used in a wide-range of industries. Manufacturing and fabrication industries use forms of NDT to ensure product quality, improve manufacturing processes and minimize production costs. You might not realize it, but chances are, you’ve been a test subject for non-destructive testing. If you’ve ever had an x-ray or CT scan – then you’ve been a test subject! Medical professionals use NDT to diagnose – most common forms include film radiography, computed radiography (CR), computed tomography (CT) and digital radiography.
Non-destructive Testing Methods
There are several variations, the six most popular are:
- Magnetic Particle Testing (MT)
- Liquid Penetrant Testing (PT)
- Radiographic Testing (RT)
- Ultrasonic Testing (UT)
- Electromagnetic Testing (ET)
- Visual Testing (VT)
