We have an extensive range of equipment available for material verification and component performance and measurement.

All of our processes are managed through a comprehensive library of procedures that allow for accurate and fluid inspection and testing processes.

We demonstrate full traceability of our materials and processes, providing detailed quality reports tailored and specific to our client’s projects. Inspection is undertaken throughout the stages of manufacture to ensure that we not only meet the requirements stipulated to us for a given project but in fact exceed them.

Goodwin employs over twenty Level II and Level III ASNT and PCN qualified personnel to carry out testing such as radiography, ultrasonic, magnetic particle and dye penetrant inspection.

Our testing engineers receive continuous training to maintain our testing capability.

With our laser measurement and scanning technology, coupled with one of the largest CMM capabilities in the UK as well as conventional measurement techniques, we are able to ensure components are manufactured to the highest possible standards demanded by our customers. We also have an array of portable CMM measuring equipment to carry out more in-depth verification of components during the manufacturing process.

Our testing facilities are supported by Suitably Qualified Experienced Personnel (SQEP) that also develop, implement and improve upon industry test criteria.


CMM Capability

The DEA Hexagon Alpha Image 25.50.15 is one of the largest available CMM capabilities in the UK. It has the ability to measure components up to 5m x 3m x 2m (x, y, z) and up to 35,000kg. Portable CMM measuring and gauging can also be undertaken using any of three Faro Gage Arms allowing inspection to take place during manufacture.

Fine Detail Verification

The Shadowgraph JT12AB is an effective measuring device which allows fast precision profile measurement of any complex detail of components.

Positive Material Identification

The NITON XL2 portable X-ray fluorescence analyser provides immediate non-destructive analysis of alloy material for both verification and product quality assurance and control purposes.

Industrial Radiography

Two linear accelerators that operating in two separate bays one of which is below ground level and has a 70 tonne lifting capacity with a 30 tonne revolving table. The dual voltage linear accelerator (6/9 MeV) is crane mounted with 360˚ rotation and 45˚ tilt at 4 metres height. Thickness ranges from 40mm up to 350mm with excellent results throughout. Goodwin employs a number of radiographers with qualifications including both PCN and ASNT.
