Non Destructive Testing Methods
We make use of a range of NDT methods and testing techniques to provide quality control and non-destructive examination services to our clients. Including:

• NEW! - Phased Array Ultrasonic Testing:
  Phased array inspection is an advanced testing method that is used to detect flaws that cannot be found with conventional NDT methods such as radiographic testing or manual ultrasonic testing. Phased array testing is capable of meeting the higher demands of advanced industries and services that we work with.


• Dye Penetrant Testing:
  This visual testing method is also known as Liquid Penetrant Testing and is used to reveal any surface breaking flaws in forged, welded or cast components by applying a dye or fluid to the specimen which then shows any flaws present. Dye Penetrant Inspection is a common NDT technique that we provide and can be used on a wide range of components.


• Ultrasonic Inspection:
  This NDT method is used to test for any internal defects and flaws in castings, forgings and welds. It can also be used for material thickness measurement. It works by sending sound waves into a material and watching how the guided waves interact with the material. Ultrasonic Testing is particularly useful in examining pressure vessels in service for power generation.


• Magnetic Particle Inspection:
  This method of NDT is used to find surface and near-surface flaws in ferromagnetic materials by using a powerful magnet to create a magnetic field around the specimen. A sensor is then used to detect the magnetic flux leakage that is generated around flaws such as cracks.


• Radiographic Testing:
  Radiographic testing is commonly used to detect internal and sub-surface irregularities in a range of components. Radiographic Inspection makes use of X-rays to inspect for flaws and discontinuities. The results are then processed on to a physical film for visual inspection by a trained radiographic interpreter. We can also digitise the image with our top of the range radiographic film digitiser which creates a digital radiography image that can be viewed on your own computer. This testing method provides a permanent photographic record of testing.
