As with all new and evolving inspection methods, good training of guided wave inspectors forms a critical part of the development of the technology. Experienced, skilled inspectors can make a significant difference in the reliability of the results that are obtained, especially in situations when any indicated defective areas cannot be measured by complementary methods. Therefore, Guided Ultrasonics Limited (GUL) has always been fully committed to developing and improving quality training modules that allow inspectors to learn as effectively as possible. We offer both classroom and on-site training, for both simple and complex applications. GUL has trained over 2,500 inspectors globally and continues to host more than 50 training courses each year. 

In addition to being an Authorized Training and Test Center for the PCN qualification in guided waves (managed by the British Institute of Non-Destructive Testing - BINDT), GUL has maintained its own training and certification program that is specific to GUL equipment. The existing GUL scheme is now being transitioned to a new scheme that is managed by Guided Ultrasonics Ltd. Training (GULT), a division of Guided Ultrasonics Ltd. GULT fulfils the role of a certification and qualification body. GULT may also perform training as an authorised training organisation provided that impartiality is maintained, in accordance with ISO 17024:2012. Success in the qualification examinations leads to the award of GULT certification covering Guided Wave Testing using GUL equipment only.

Rental Equipment

Rental of equipment to existing clients, so they can inspect unusual sizes or meet peaks in demand.

Repairs and Servicing

A repair and calibration service to ensure that equipment continues to perform to its maximum.

Spares and Accessories

Spares parts for general equipment maintenance, as well as accessories for specific requirements.

First developed in 2005 with the assistance of Network Rail, the G-Scan rail instrument sends guided waves down the length of a rail to look for any areas of cross section change. The guided waves that are created in the rail are able to detect cracks and corrosion in any section of the rail, including the 'foot' and 'toe'. 

Because of this ability to detect corrosion areas that are normally hidden from higher frequency methods that access the rail from the head, the G-Scan system is often used to inspect level crossings that are susceptible to foot corrosion, but are difficult to inspect without disrupting both rail and road traffic. Guided wave inspection performed from outside of the level crossing can inspect the section while the road is still fully operational; rail traffic is often not disturbed if the period between trains is long enough. The results allow you to rank the crossings, extending the mandatory lifting time for some crossings, prioritising replacement for others.

The current generation of the G-Scan uses the Wavemaker® G4 electronics and the WavePro software to collect, analyse, and report the guided wave data.

Available Versions:

Standard sizes for the G-Scan unit are CEN50, CEN54, CEN56, and CEN60, although specials can be produced for a variety of rail sizes ranging from 36 kg/m to 61 kg/m.
