Application Notes
High Temperature Hydrogen Attack (HTHA)
27th March 2020
High temperature hydrogen attack (HTHA) is an irreversible deterioration of the mechanical properties of steel due to the reaction of hydrogen with carbon at temperatures in excess of 200°C.
Application Notes
Ultrasonic Rail Solid Axle Inspection with the Sonatest Wave
27th March 2020
This type of inspection needs to be done after manufacturing of the axles, as well as multiple times throughout their working life.
Application Notes
Wave Nozzle Inspection
27th March 2020
In an A-Scan only view, signals can be difficult to interpret. Small inaccuracies in probe positioning or the angle of reflection may place a signal as a defect in the weld when in fact it is a reflection from the internal wall.
Application Notes
Low Frequency PAUT Inspection of GFRP
16th March 2020
Certain heterogeneous materials can be highly attenuative to ultrasound. As a result, lower frequency probes are required, especially for thick sections which otherwise can be difficult to inspect.
Application Notes
Austenitic Stainless Steel Solution DAAH – Dual Linear Array Probe
13th February 2020
300 series stainless steels are the most common sub-group of austenitic steels and are used in a large variety of processes and industries, typically for corrosion resistance of high temperature service. Comprehensive inspection techniques are vital to ensure safe operation.
