NDT Inspections

Structures - Components - Machinery

What is NDT and how does it work? it stands for non-destructive testing, it is a way of testing without destroying a component or structure. The component or structure can continue to be used and the non-destructive testing method has done no harm. In today's world where new materials are being developed, older materials and bonding methods are being subjected to higher pressures and loads, NDT ensures that materials can continue to operate to their highest capacity with the assurance that they will not fail within predetermined time limits. NDT can be used to ensure the quality right from the raw material stage through fabrication and processing to pre-service and in-service inspection. 

3D/IR Thermal Imaging

Thermography is a non-contact technology that measures or “sees” infrared wavelengths emitted from objects, and then converts the temperature information into an image. The image features a colour palette that represents the temperature range of the image displayed. Hot spots or a rise in temperature often indicate problems or potential failure.


When a sound wave strikes an object or material, it bounces back, or echoes. In an ultrasound examination, a transducer both sends the sound waves into the material and receives the echoing waves. When the transducer is pressed against the material, it directs small pulses of inaudible, high-frequency sound waves into the material. Ultrasound ABC scan is used on metallic and composite structures.

Ultraviolet Light

Ultraviolet Inspection lights are used in Non-Destructive Testing (NDT) for fluorescing fluorescent magnetic inks and fluorescent dye penetrants to detect any anomalies present in composites and metallic components. 

Dye Penetrant

The principle of liquid penetrant testing is that the liquid penetrant is drawn into the surface-breaking crack by capillary action and excess surface penetrant is then removed; a developer (typically a dry powder) is then applied to the surface, to draw out the penetrant in the crack and produce a surface indication.
