Welcome to Focus NDT

Focus NDT provides a broad range inspection services for UK Businesses in the Engineering, Transport, Petrochemical, Gas, Nuclear, Manufacturing and Aerospace industries. Established in 1993, we are the recognized leader in Non-Destructive Testing (NDT) and inspection activities. Our Services include: non destructive testing, liquid penetrant testing, ultrasonic testing, and magnetic particle inspection. Focus NDT prides itself on its Rapid Response and Complete Customer Satisfaction.

Ultrasonic Inspection is used as method of testing for flaws. We introduce sound waves via an ultrasonic source, measuring the reflection echoes to determine the thickness of the material and the distance to the discontinuity. We are leaders in Ultrasonic Inspection, with our service second to none. Please contact a member of our team via phone or email with any qeations you may have.

Magnetic particle inspection is used for the detection of surface and near-surface flaws in ferromagnetic materials. We apply a magnetic field to the test item, and then using fine magnetic particles (usually in carrier liquid form) we are able to create a visible flaw indication. For more information about MPI please visit our website now.

We apply a visible or fluorescent dye to the surface of the test item. This will penetrate discontinuities and after the component is dried, we draw out the liquid onto a white absorbent coating to clearly identify all flaws on the surface of the product. method is suitable for any non ferrous components or material that is non absorbent. Typical applications are forged, cast or welded products.

Eddy Current can be used in two different manners, Firstly for finding surface and subsurface flaws, and Secondly for determining different metallurgical characteristics. Eddy current measures changes in the impedance of an electromagnetic coil as it is scanned over a surface of conductive material. When we scan over a discontinuity the magnetic field created by the Eddy currents is distorted and changes the load on the coil. This directly affects the impedance of the coil and these are then measured in order to trace possible flaws.

We use a source of ionising radiation positioned at on one side of the test item, and a photographic film placed the other side. The radiation is partly absorbed during transmission and differences in material thickness and / or absorption qualities are recorded on the film providing a full-size image that shows internal detail. The higher the Material density, the more radiation absorption will occur. Radiography provides a non-destructive method of detecting hidden flaws and is particularly good at detecting volumetric flaws such as voids, gas pores and solid inclusions. It is also good measuring the length and width of flaws; however it cannot be used to measure through-thickness of defects.

Focus NDT also provides a range of other Test and Inspection services including:

• Hardness Testing
• Test Block Calibration
