GFS NDT was established in the Naval Base WA, in 2020. With a focus on providing NDT and inspection services to Australia’s fabrication, mining, and oil and gas industry sectors.

The founding management team established the business because we wanted to create an environment and culture, that technicians and inspectors want to be part of. GFS NDT believes their people are their differentiators and are at the center of everything they do, this enables them to provide an unrivaled service to their clients.  

GFS NDT always strives to build long-term relationships with clients, ensuring a quality of service that sees their clients returning to them time and again.

Products & Services
Non-Destructive Testing

Magnetic Particle Testing (MT) 

This NDT process uses magnetic fields to find discontinuities at or near the surface of ferromagnetic materials. The magnetic field can be created with a permanent magnet or an electromagnet, which requires a current to be applied. 

The magnetic field will highlight any discontinuities as the magnetic flux lines produce leakage, which can be seen by using magnetic particles that are drawn into the discontinuity.  

Liquid Penetrant Testing (PT) 

Liquid penetrant testing involves the application of a fluid with low viscosity to the material to be tested. This fluid seeps into any defects such as cracks or porosity before a developer is applied which allows the penetrant liquid to seep upwards and create a visible indication of the flaw. Liquid penetrant tests can be conducted using solvent-removable penetrants, water-washable penetrants, or post-emulsifiable penetrants. 

Radiographic Testing (RT) 

Radiographic testing uses radiation passed through a test piece to detect defects. X-rays are commonly used for thin or less dense materials while gamma rays are used for thicker or denser items. The results can be processed using film radiography, computed radiography, computed tomography, or digital radiography. Whichever method is used, the radiation will show discontinuities in the material due to the strength of the radiation. 

Ultrasonic Testing (UT) 

Ultrasonic Testing entails the transmission of high-frequency sound into a material to interact with features within the material that reflect or attenuate it. Ultrasonic testing is broadly divided into Pulse Echo (PE), Through Transmission (TT), and Time of Flight Diffraction (ToFD). 

Eddy Current Testing (ET) 

Eddy current testing uses an alternating current coil to induce an electromagnetic field into the test piece, alternating current field measurement and remote field testing both use a probe to introduce a magnetic field, with RFT generally used to test pipes.
