Radiographic Testing involves the use of penetrating X or Gamma radiation to examine parts and products for imperfections. An X – ray machine or radioactive isotope is used as a source of radiation. Radiation is directed through a part onto the film. When the film is developed, a shadowgraph is obtained that shows the internal soundness of the part.

Non-destructive testing allows us to examine structures, materials or components without damaging or destroying the object being tested, and provides a means to ensure product reliability and quality. There are an assortment of NDT techniques used throughout a broad cross-section of industries. The Four most widely used techniques being Radiography, Ultrasonic, Liquid penetrant and Magnetic particle testing.

Non-destructive testing

Non-destructive testing is used for in-service inspection and for condition monitoring of operating plant. It is also used for measurement of components and for the measurement of physical properties such as hardness and internal stress.

Around the world, NDT technicians do thousands of inspections and tests every day to assess new product quality, equipment condition and reliability. By doing so, they help prevent failures in nuclear power, aviation, transportation, oil and gas, petrochemical plants and anywhere else where public safety or the environment could be significantly impacted. All without destroying or disassembling the item that is being inspected.
