Ultrasonic Inspection |
| Ultrasonic inpsection is a method which utilises high frequency soundwaves to perform volumetric examinations of materials.
Ultrasonic testing is used most commonly to detect sub-sufaces flaws but in some instances can be used to detect surface flaws as well.
Ultrasonic testing works by introducing soundwaves in to the material under test, these waves then propogate through the material.
Any discontinuity in the wave path will cause part of the sound wave to be reflected back, which is then detected and displayed on the ultrasonic inspection equipment.

Magnetic Particle Inspection |
| Magnetic particle inspection is a method used for detecting surface breaking flaws (and in some cases sub-surface flaws) in ferromagnetic materials. The object under test is magnetised and a ink or powder containing ferromagnetic particles is applied to the test area. This then permits the identification of surface breaking flaws.

Dye-penetrant Inspection |
| Dye-penetrant testing is another method used to detect surface breaking flaws, which is not restricted to just
ferromagnetic materials but all non-porous materials.
The method is based on a liquid penetrant being applied to the test area and using the capillary effect to draw the dye in to any
surface breaking flaws. Once excess penetrant has been removed from the test piece a coat of developer is applied causing the penetrant in any
surface breaking flaws to 'bleed' out to the surface allowing for the flaw to be easily identified. Click here for more information on the penetrant testing services that we provide.

Hardness Testing |
| Hardness is the property of a material that enables it to resist plastic deformation. Hardness testing is a method used to determine the hardness of a metal.
The Brinell method of hardness testing consists of indenting the test material with a hardened steel ballbearing of known diameter at a known force. Using a microscope the diameter of the indentation is read off and by means of a chart can be converted into the materials hardness Brinell.
