Our NDT services are highly flexible including short notice availability for in house or on-site testing. From batch testing of multiple components, to ‘in-situ’ testing of large fabrications, we aim to provide a swift and satisfactory response to all enquiries and requests. Our technicians work to procedures using detailed method statements and test instruction sheets that are both written and approved by an ISO 9712 Level 3 and have also gone through a rigorous peer review process by external Level 3 NDE Engineers.

WDC can offer rapid ‘ad-hoc’ or project length support in the following techniques:

Magnetic Particle Inspection (MPI)

MPI is used for the detection of surface breaking and slightly sub-surface (up to 2mm) discontinuities on ferrous materials. On-site testing is carried out using electromagnetic yokes and permanent magnets producing induced magnetic flow.

Liquid Penetrant (DPI)

Dye penetrant Inspection or Liquid penetrant inspection is used for the detection of surface breaking discontinuities on ferrous and or non-magnetic materials. One thing we are unable to test is any material which is porous.

Fluorescent and colour contrast penetrants are available to be used in the following methods:
Water washable
Solvent removable

Ultrasonic Testing (UT)

Ultrasonic testing is used for the detection of volumetric discontinuities in ferrous and non-ferrous products (forgings and castings etc.), and welds in magnetic and non-magnetic materials. It is also capable of checking thicknesses of materials.

Visual Testing (VT)

VT involves visual observation of the surface of a test object to evaluate the presence of surface discontinuities against a code or international standard. VT inspections can be conducted by Direct Viewing, using line-of-sight vision, or may be enhanced with the use of optical instruments such as magnifying glasses, mirrors, fiberscopes, and computer-assisted viewing systems (Remote Visual).

Visual examination can be used to assess a great number of discontinuities such as Corrosion, misalignment of parts, physical damage and cracks.


WDC aim to be flexible to our customers individual needs when it comes to reporting. We can offer our in-house report templates, or we can adopt to our customers project specific report templates.

Our NDT is fully managed and coordinated by a technical engineer with all NDT reports carefully assessed prior to submission.
We aim to deliver reports to you within 24 hours of inspections taking place, keeping your project documentation in line with your build progress.

Our people

All of our NDT Personnel representing WDC on site have been carefully selected and assessed ensuring each are qualified to a minimum requirement of ISO9712 Level 2.
