Visual Inspection

The oldest of all the methods. Components are scanned
visually, sometimes with the aid of low or high power lenses,
fibrescopes, cameras and video equipment, to determine
surface condition.

Ultrasonic Inspection

Ultrasonic inspection uses high frequency sound waves to detect imperfections or changes in properties within the materials. It can also be used to measure the thickness of a wide range of metallic and non-metallic materials where access from one side is available.

Eddycurrent Inspection

In eddy current testing electrical currents are generated a conductive material by an induced magnetic field. Distortions in the flow of the electric current (eddy currents) caused by imperfections or changes in a material’s conductive properties will cause changes in the induced magnetic field. These changes, when detected, indicate the presence of the imperfection or change in the test material.

Magnetic Particle Inspection

Magnetic Particle Inspection is used  to identify surface and near surface discontinuities in ferromagnetic materials such as steel and iron. The  Technique uses the principle that magnetic lines of force (flux) will be distorted by the presence of a discontinuity. Discontinuities (for example, cracks) are located from the flux distortion following the application of fine magnetic particles to the area under test.

Liquid Penetrant Inspection

In Liquid Pentrant the test object or material is coated with a visible or fluorescent dye solution.  The excess dye is removed from the surface and a developer which acts like a blotter is applied drawing penetrant out of imperfections open to the surface. With visible dyes, the vivid colour contrast between the penetrant and the  developer is used. With fluorescent dyes an ultraviolet lamp is used to make the ‘bleed out’ fluorescence brightly allowing the imperfection to be seen readily.

Radiographic Inspection

Radiography uses and x-ray device or radioactive isotope as a source of radiation which passes through the material and is captured on film or digital device. After processing the film an image of varying density is obtained. Possible imperfections are identified through density changes.

Infrared & Thermography

Thermography enables the thermal profile of an item, machine or building to be presented in a graphic from which allows a working temperature assessment to be derived. From this, variations in the material or component temperature are identified, enabling working limits or corrective actions to be identified.

Vibration Analysis

A fundamental requirement in all vibration work, whether it is in the design of machines which utilize its energies or in the creation and maintenance of smoothly running mechanical products, is the ability to obtain an accurate description of the vibration by measurement and analysis.
