Roll Inspection -  Ultrasonic Surface Wave Technology

The Ultrasonic Surface Wave (SW) roll inspection system is developed to detect those defects that cannot be detected by the standard Eddy Current Technology or the standard Ultrasonic Technology, because these defects are on, to close to, or just beneath the surface. With SW it is possible to detect cracks and inclusions up to a depth of 5mm (0.20"). It is not possible to detect bruising and pinches, this can only be done by ET. Therefore we advise to use Surface Wave always in combination with our standard ET. Additionally it can also be combined with an UT inspection system depending on the wishes for what has to be detected.

Surface wave can be added to the COMBI System, resulting in a full coverage of the roll working area.
