NDT Inspector

Definition - What does NDT Inspector mean?

NDT Inspector is an individual responsible for carrying out NDT techniques to improve the product reliability and manufacturing qualities. Non-destructive testing (NDT) is a technique of analysis used in industries and science to evaluate the properties of a component, material and system without causing any damage. The inspector is supposed to regularly inspect the components and structures in the industry for defects or faults and discontinuities that can reduce the structural integrity which can result in failure. NDT is a highly valuable technique that saves time and money in research, product evaluation and troubleshooting.

Petropedia explains NDT Inspector

The NDT inspector may use methods that rely on the use of electromagnetic sound, radiation and inherent properties of the material to examine the samples. The inspector uses these techniques in a variety of settings which cover a vast range of industrial activity. The inspector may use the following applications:

  • Weld Verification: Welds are generally used in the manufacturing process to join two or more metal parts. Welds can be verified using NDT techniques like industrial CT scanning using gamma rays or X-rays, liquid penetrant testing, ultrasonic testing and magnetic particle inspection.
  • Structural Mechanics: A structure can be a complex system that undergoes different loads during its lifetime. In NDT, the structure undergoes a dynamic input like a tap of hammer or controlled impulse. The properties like acceleration or displacement at different points of structure can be measured as the corresponding output.
