A new fabrication concept of EMAT-SH and SV Probes for a frequency range of
1 MHz to 2.5 MHz has been developed.
Models of arrays with up to 6 transmitter and 6 receiver
elements in a housing of 40 mm x 40 mm x 30 mm are available. Probe
modifications for curved geometries of a radius as low as to 5.4 mm are
possible.
The following examples are discussed:
Wall thickness measurement and flaw detection.
Results of sound field measurements of SH-Wave Probes
Flaw detection in an austenitic pipe weld using SH-Wave Probes
Flaw detection in a non-ferrous pipe (10.8 mm x 0.8 mm)
