Automated

The WeldROVER scanner is the ideal automated scanning option for inspection of carbon steel weld using one pair of PA probes and up to three pairs of TOFD probes. It provides a faster and more stable movement of the probes for higher rate and more accurate data acquisitions.

For efficient automated scanning of carbon steel welds in difficult-to-reach areas, the motorized SteerROVER scanner enables you to steer the scanner at a distance. Use the SteerROVER scanner with its rugged touch-screen handheld controller to perform reliable phased array (PA) ultrasonic testing of circumferential and longitudinal welds. The optional RECON camera kit assists in navigating the scanner, keeping the weld well centered, and helping ensure that the probes remain in contact with the surface.

Manual and Manual Encoded

The weld can be scanned manually using one PA probe that can be encoded by attaching a Mini-Wheel encoder or by using a VersaMOUSE hand scanner.

Techniques

Phased array technique allows multiple beam angles, beam types and beam offset to be generated electronically. This allows greater flexibility for easy adaptation to different type of welds.

Conventional UT technique can be an alternative to phased array when very high speed is required or when cost is preferred over flexibility.

TOFD can be used alone for fast and simple inspection or as a complementary technique to pulse-echo.

Combining phased array and TOFD techniques offers the best performance for most carbon steel weld inspection. Both techniques complete each other for excellent imaging, best POD, and flaw characterization.
