Pitting detection with TFM and MANTIS

Here is a comparison of a linear scanning using 8 elements focused close to the backwall and a TFM using 64 elements with 5L64 probe. The gain is set to […]

Austenitic welds

Ultrasonic inspection of austenitic welds is qualified for in-service inspection since beginning of 2000’s. Implementation of the solution based on the GEKKO associated to DMA probe makes work easier and […]

PAUT T-joint inspection

  Crack detection in a T-joint using GEKKO. We are looking at a 5-mm under-bead crack in one of the fillets. The probe is positioned along the branch on the […]

Inconel weld-inspection

Using Total Focusing Method (TFM) for the inspection of inconel weld, a extended vizualisation area is obtained. Defects are detected close to the top and bottom surfaces. ©Karl Deutsch

Weld inspection

This article shows a video of a multi-group weld inspection, using 2 phased-array and a pair of TOFD probes. With a PRF up to 20 kHZ and the streamlined CAPTURE […]

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. ©Karl Deutsch

Flange corrosion

TFM and PAUT combined on flange face corrosion: A dedicated application developed by Buffalo Inspection. GEKKO and the TFM function allows high POD and clear result interpretation.    

Cladded samples

GEKKO can inspect cladded materials using dual matrix arrays and/or TFM with the full 64-element aperture.

High temperature hydrogen attack (HTHA)

HTHA damage is detected using AUBT method (Advanced Ultrasonic Backscattering Technique) that evaluates the frequency and velocity dependence to a non-damaged area This technique requires skillful operators to recognize backscatter […]

Offshore bolt inspection

In Brazil, Sub Sea Services is using the phased-array flaw detector and imager GEKKO to inspect bolts in offshore conditions. A large range of bolts with different geometries are inspected […]

Nozzle inspection on GEKKO

By Frédéric REVERDY, Business Development Manager in M2M Ultrasonic Inspection of nozzles has always been a challenge due to the geometrical complexity of the component, the changing surface curvature and […]

Cracks in clads

It is possible to detect cracks in the cladding using TFM by focalizing the energy everywhere and using a large aperture.  


Hydrogen Induced Cracking (HIC)

The molecular hydrogen formed in situ produces blisters, and adjacent blisters subsequently are connected on different planes in the metal.HIC can be confused with laminations or volumetric inclusions.Typical detection with […]


Corrosion can induce wall thickness and pitting. Challenge is to map fast with high accuracy and high probability of detection.The GEKKO, associated to 2 axis-scanner, offers the best solution for […]

Field inspection of a nozzle using GEKKO

By Frédéric REVERDY, Business Development Manager in M2M   Even without scanner it is possible to have a cross-section by simply entering the position of the probe making it possible […]
