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 […]
MANTIS
Offshore Wind Power T-joint construction weld
Application of TFM for defect sizing in welded joints. These below pictures show T-joints at the offshore windmill construction. The material thickness to inspect is 40 mm to 60 mm. Here […]
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 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 […]
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
PMMA inspection
This video shows an electronic scanning of a PMMA (polymethyl methacrylate also called acrylic glass) plate using the flaw detector GEKKO, a 5 Mhz probe by Imasonic and the Bras […]
Small diameter pipe inspection
In this case, a cylindrical reconstruction is being done for small diameter pipe inspection using sizing with corner effect mode (TTT) for better defect sizing. Both TFM technique and sectorial […]
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 […]
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 […]
