Surface Inspections

No items found.

Provides fast inspection and detection of surface defects. Unlike Eddy Current, it permits inspecting without direct access to the area inspected and cover large areas with a limited number of sensors.


  • Non-Contact EMAT technique.
  • Available for any material thickness and part geometry. Surface waves will follow part curvature.
  • Reflection and attenuation techniques available depending on the application and type of defect.
  • Ideal for detection of defects perpendicular to the scanning direction (e.g. rolling defects).
  • Detects surface cracks as small as small as 127µm (0.005”).
