Rapidscan Technique
Ultrasonic testing. Fast and versatile C-scan inspection instrument
General inspection capabilities
* 128 channel Ultrasonic array in wheel probe
* A, B, C, D scan mode
* Mainly detects laminar defects
* Can be used on metals to detect corrosion (hidden, inter-laminar and exfoliation) and to detect cracks.
* Additionally can be used to assess Adhesive bonding and on composites to asses impact damage and de-laminations.
* Additionally can scan for Adhesive bonding, Fibre wrinkling and Porosity.
* Water filled flexible rubber tyre used for array coupling. This have improved surface conformance over standard probes.
* Wheel probe can also be integrated into automated system

Rapidscan instrument, wheel probe and typical scan display
Inspection limitations
- Only large areas suitable for testing.
- More suitable for detection of laminar defects in composites.
- The cable between detector and probe cannot be longer than 10m so rope-access might prove difficult.
Access requirements
- General equipment weighs 12 kilos and the probe 3kg.
- For large plate surfaces access to allow scanning should not be an issue.
