The backscatter technique is used for the detection of suspicious areas affected by hydrogen attack. It enables the creation of backscatter patterns and the evaluation of directional and frequency dependences.

Velocity ratio measurement is applied for the confirmation of the findings from the backscatter technique. It allows the measurement of the percentage of hydrogen attacks and supports the differentiation between small inclusions and HTHA.

Time of flight diffraction is used for the inspection of weld material and for the detection of macro and micro cracks.

Phased array is applied for the inspection of nozzle welds.
