nozzle inspection.
 

> 3-AXIS ENCODED NOZZLE INSPECTION USING GEKKO

With the possibility to define nozzle type geometries on-board, the GEKKO can be used for 3-axis encoded nozzle inspections. Sscan images superimposed on the Cross-section overlays of the nozzle are calculated as the operator moves the probes.

  • TFM offers a better SNR closer to the surface 
  • Higher resolution using TFM
  • Better accuracy on swoosh shapes with TFM

Small defect detection for carbon steel specimen inspection.


 

> COMPOSITES INSPECTION USING 3-AXIS ENCODED SCANNER

The Gekko is the only portable unit compatible with 3-axis scanners making it possible to use with mouse type scanner for very fast scanning of large plates.



 


> EXTENDED VIZUALISATION AREA

Inconel weld-inspection with TFM technique. Defects are detected close to the top and bottom surfaces.
 

 

 

 

 
 

cylindrical reconstruction.


> DEFECT SIZING

Small diameter pipe inspection using sizing with corner effect mode (TTT). Both TFM technique and sectorial scan are illustrated. For outside diameter defects, both modes account for the rebound off the inner curved-surface to display a scaled image.

> TFM / E-SCAN COMPARISON ON CORROSION WITH GEKKO

This video shows a corrosion mapping inspection using a manual scanner and real-time Total Focusing Method. Then it compares TFM and Electronic scanning for differents defects in corrosion, using the same probe position.
