EMAT techniques permit the detection of weld defects with great sensitivity using both Shear Vertical and Shear Horizontal sensors. UT and PAUT permit detection and sizing of defects.
Merkmale
EMAT
- Berührungslose EMAT-Technik.
- Permits fast screening without couplant of welds of any thickness.
- Geeignet für Temperaturen von -30ºC bis 350ºC.
- Shear waves with horizontal polarization (SH) permit inspection of austenitic materials without mode conversion.
- Shear waves with vertical polarization (SV) permit inspection of ferromagnetic materials with similar detection capabilities as piezoelectric UT (no sizing available).
- Rollensätze, Drehgeber und Adapter für verschiedene Anwendungen.
PAUT
- Superior focusing and steering capabilities.
- Sowohl interne als auch externe Defekte können erkannt und dimensioniert werden
- Permits covering large areas with array transducers.
- Inspection available from either side of the weld or across the weld in transmission.
