This example of a tree root blade shows that geometry echoes are present and the CAD overlay makes interpretation easier. With GEKKO equipment, it is possible to import 2D CAD files as overlays to help interpret echoes.

BLADE INSPECTION WITH HALF-SKIP TFM
THICK BOILER TUBE INSPECTION
Thick boiler tube application (150 mm), sizing of small defects (1.5 mm).
64-element aperture allows to focus the beam and see the tip diffraction.
BOILER TUBE INSPECTION
GEKKO can use scanners for boiler tube inspection and use two 32-element PA for the inspection from both sides.
The Gekko can go up to 20 MHz and thus inspect thinner walls.
SCREW THREAD INSPECTION
27-mm long screw thread inspection with TFM technique. Optimal resolution is obtained along the thread.
Probe: PA, 5 MHz, 64 elements and a Pitch of 1.8mm.
