In most industries where outage time is important short and accurate analysis time of surface anomalies and indications is essential. For these customers there is no time to deal with fake news.

The Replica Molding Technique (RMT) used by WesDyne has been developed to deliver fast and accurate surface measurements both submerged and in open air. The technique enables surface geometry measurements, profile measurements and defect detection with very high accuracy. RMT has been validated and qualified for detection of submerged 3µm wide and 1.5mm long surface breaking defects in the Swedish nuclear industry. Furthermore, RMT is suitable for and commonly used in combination with planned inspections for defect detection, in support of repair work (e.g. verification of boat sample cavities) and for wear measurements of submerged parts using 3D laser scanning and modelling of the retrieved replica. Unlike other surface techniques like dye penetrant, 3D laser scanning and eddy current techniques RMT is not affected by complex geometries, under water challenges or radiation levels.

One of the major benefits of RMT is the rapid preparation and deployment of equipment and NDE expertise saving significant critical outage time.
