Corrosion mapping identifies and maps variations in material thickness due to corrosion. Results for corrosion mapping provide a high degree of repeatability and the advantage of position and size data for every flaw. This can be compared to repeat scans of the same area to track flaw growth or corrosion rates both generally and for individual pits.

The Sonatest range of standard and high-temperature corrosion mapping transducers complement the compression wave probe range and are compatible with Sonatest automatic or semi-automatic scanners. They are housed in a durable steel case with side entry connections for ease of use. They can be used as a stand-alone transducer for manual inspections or fitted with a detachable light-emitting diode utilized with various manufacturers’ video tracking systems.
