Over the last 40 years, TWI has been at the forefront of the research, development and application of many non-destructive testing (NDT) technologies. The driving force behind these developments has been industry's need for techniques that would accurately locate, characterise and size flaws in every type of component and structure, from printed circuit boards to offshore platforms and from medical implants to nuclear reactor pressure vessels.

The magnetic particle method of Non-Destructive Examination was developed in the USA, in the 1930s, as a way to check steel components on production lines. The principle of the method is that the specimen is magnetised to produce magnetic lines of force, or flux, in the material. If these lines of force meet a discontinuity, such as a crack, secondary magnetic poles are created at the faces of the crack. Where these secondary magnetic fields appear at the surface of the metal, they can be revealed by applying magnetic particles, as a powder, or in a liquid suspension, to the surface. The particles are attracted to the flux leakage and clump round the flaw, making it visible. The particles may be black, or coated with a fluorescent dye to increase their visibilty.
The magnetic flux lines should be at right angles to a flaw to give the best indication, as this creates maximum flux leakage. This governs the choice of a suitable magnetising technique. Often, more than one technique must be used to give a complete inspection.
A flaw attracts more particles if it cuts more magnetic lines of force, so the ability to show a flaw depends on the depth of the flaw, the angle of the flaw to the lines of force, and the magnetic field strength induced during magnetisation. The method is limited to ferromagnetic materials - iron, cobalt and nickel - as other paramagnetic and diamagnetic materials cannot hold a flux which is strong enough to attract particles.

The complex geometry of many composite components means that inspection has to be performed manually or by slow immersion tank techniques. TWI has developed an automated inspection system comprising two six axis robotic arms, capable of working independently and cooperatively.
The robotic arms deploy end-effectors carrying ultrasonic transducers (single element and phased array), mounted into water jet nozzles that couple the ultrasound into the part. Software developed in-house generates 3D imaging of the part as well as traditional A- and B-scan data.

Alternating current field measurement (ACFM) is an electromagnetic technique used for the detection and sizing of surface breaking cracks in metallic components and welds. It combines the advantages of the alternating current potential drop (ACPD) technique and Eddy Current Testing (ECT) in terms of defect sizing without calibration and ability to work without electrical contact respectively.

Phased array ultrasonic systems utilize multi-element probes, which are individually excited under computer control. By exciting each element in a controlled manner, a focused beam of ultrasound can be generated. Software enables the beam to be steered. Two and three dimensional views can be generated showing the sizes and locations of any flaws detected.

The Intacom programme is a series of projects based on the development of robotic inspection systems that is being led by TWI’s Advanced Non-destructive Testing Centre in Port Talbot, South Wales. The programme’s overall aim is to reduce the cost of inspection of complex geometry components for the aerospace industry. The first phases of the project delivered a prototype automated inspection cell using two 6-axis robot arms to inspect highly curved components in a fraction of the time usually taken by other automated NDT systems. It incorporated custom developed advanced ultrasonic testing technology to provide 3D imaging of parts that, in many cases, could not be inspected in any other way.

Eddy Current Testing is one of several Non Destructive Testing methods that use the ‘electromagnetism’ principle. Conventional Eddy Current Testing utilised electromagnetic induction to detect discontinuities in conductive materials. A specially designed coil energised with alternating current is placed in proximity to the test surface generating changing magnetic-field which interacts with the test-part producing eddy current in the vicinity. Variations in the changing phases and magnitude of these eddy currents is then monitored through the use of receiver-coil(s), or by measuring changes to the alternate current flowing in the primary excitation-coil. The electrical conductivity variations or magnetic permeability of the test-part, or the presence of any discontinuities, will cause a change in eddy current and a corresponding change in phases and amplitude of the measured current. This is the basic principle of eddy current inspection.

Teletest® was the first commercially available system to utilise long-range guided wave ultrasonic testing for detecting corrosion in pipelines. TWI developed the technology in response to requests from Industrial Members in the Oil, Gas and Petrochemical industries. These companies required an NDT method capable of detecting corrosion in pipes and pipelines at areas inaccessible for inspection by conventional NDT methods, i.e. insulated and sleeved pipework, or pipelines running under roads or elevated on pipe racks, etc. The original Teletest® equipment has been replaced by a system with greatly enhanced capability and the flaw detector is sold under the Teletest Focus trade mark.

Before taking any sophisticated ultrasonic equipment into the field, it is important to predict the performance of the system on the specific component to be tested.
In the past, this was usually done by carrying out tests on mock-ups of the component in the laboratory. However, more recently, numerical modelling of the interaction of ultrasound with the component has found an increasing role.

Thermography uses a camera containing large numbers of infrared sensors, which can detect and measure small temperature differences. The image showing these differences can be downloaded to and displayed on a PC, normally as a colour or grey-scale map.
There are two basic types of thermography – passive and active. In passive thermography, the camera is simply pointed at the test piece and from the thermal image a temperature map is constructed. Active thermography involves heating the surface of the object rapidly using an external heat source and observing how the temperature decays with time. Flaws in the material show up by variations in the temperature decay rate.

TWI’s CrystalTM software makes ultrasonic inspection of industrial structures using Full-Matrix Capture (FMC), Virtual Source Aperture (VSA) and Plane Wave Imaging (PWI) easy.
The fully automated software delivers an intuitive interface for ultrasonic inspection techniques with high defect detection and sizing accuracy capabilities and real time inspection via planar or complex geometry structures.
These capabilities mean that Crystal can be integrated into in-service and production environments within industries including nuclear, defence, oil and gas, aerospace and rail.
Developments in computer hardware mean that real time implementation of total focusing method (TFM)-based algorithms such as full matrix capture, plane wave imaging and virtual source aperture are now possible. Each of these algorithms post processes the ultrasonic data to synthesise a PA focus spot at every pixel in an image, giving a fully focussed and easy-to-interpret image.
A range of inspection calibration settings and the ability to save and analyse data following inspection alongside a range of analysis and reporting tools makes the whole inspection and reporting task easier to complete.
