Consultancy
Wavelength
NDT's consultancy capability lies with Richard Freemantle who has
19 years experience in non destructive testing and ultrasonic science
and technology.
Wavelength
NDT can conduct small feasibility and demonstrator projects in any
aspect of NDT technology through to large scale R&D projects
involving technique development, validation and procedure writing.
As an independent contractor, with no ties to a particular product
range, we are able to advise on equipment and techniques purely
on their merit and suitability to the application. We firmly believe
in a strong customer relationship and, if required, R&D projects
can be carried out at the client's premises with Wavelength NDT
working with your engineers and NDT technicians.
Wavelength
NDT have worked on many types of project including:
- Providing
second opinions on inspection work and advising clients on how
to evaluate the inspection results. This includes helping the
client to develop an appropriate acceptance criteria for defects
based on stress and design analysis of the structure.
- Demonstrating
the capability of NDT methods and developing inspection techniques
for the assembly of carbon fibre primary aerospace structures.
This includes developing inspection techniques suitable for handheld
thickness gauges through to advanced phased array inspection of
complex geometries.
- Developing,
validating and preparing an advanced inspection technique for
the inspection of fibre waviness in carbon and glass fibre pre-preg
laminates. This includes modelling work to predict the sizing
capability of the method and optimise the inspection parameters.
- Developing
phased array inspection methods for complex shaped composite parts.
This includes developing suitable coupling methods which could
be easily deployed for production inspection.
- Evaluating
the deployment of Full Matrix Capture phased array techniques
for the inspection of engineering structures. This includes advising
the client on how to prepare suitable calibration and reference
specimens in order to validate the technique they had developed.
