Aerospace NDT Details

Non-Destructive Testing

Comprehensive NDT is an integral part of our 'One Stop Shop' service for defence and aerospace customers. At our Cardiff site, we have facilities for Magnetic Flaw Detection, Dye-Penetrant Inspection, Etch Inspection, Hardness Testing and Optical Microscopy. The high level of staff qualification and equipment standards ensures full compliance to prime contractor specifications, on site and without the delays associated with using an outside service.

Magnetic Particle Inspection (MPI) or Magnetic Flaw Detection (MFD)

For detection of surface and sub-surface imperfections on ferromagnetic materials, including materials that have been treated with a non-magnetic coating up to 50 microns (0.002") in thickness.

Liquid Penetrant Inspection (LPI) or Penetrant Flaw Detection (PFD)

Utilising fluorescent techniques for the detection of surface imperfections and conditions on all materials, regardless of their mechanical or material properties, such as metals, plastics and composites.

Etch Inspection

Used for detecting grinding abuse, particularly in Hard Chrome Plating.

The technique involves a sequence of acid etches which highlight the soft or hard phases produced by poor and inconsistent grinding.

The parts are inspected in natural light, the etch revealing the defects as white areas.

Heat-Treatment

Poeton have a wide range of fully calibrated ovens for the precise heat-treatment sequences specified for stress-relieving and de-embrittlement of critical aerospace and defence parts. This includes pre- and post-treatment of parts that are being chrome plated, cadmium plated or treated by any process that might bring the risk of hydrogen embrittlement.

We can inspect parts up to 3 meters, so that we can meet the volume and length demands of most aerospace and defence components.

We also have a full technical support laboratory, with Optical and Scanning Electron Microscopy, Metallography, Atomic Absorption Spectroscopy, Wear and Corrosion Testing.  Please see our Technical Assistance Section for additional information.
