Olympus Introduces the WeldROVER Motorized Scanner for Nondestructive testing

March 02, 2009 -- Olympus is pleased to introduce the WeldROVER TM motorized scanner for nondestructive testing (NDT) on metal plate, pipes, vessels and welded components from 4 inches (100 mm) in diameter to flat surfaces and on longseam welds from 30 inches (750 mm) in diameter or larger. The WeldROVER can be used with the modular OmniScan MX flaw detector or TomoScan FOCUS LT to provide phased array (PA), time-of-flight diffraction (TOFD), and advanced conventional ultrasound (UT) capabilities for both the basic and advanced level inspector.

The WeldROVER is part of the PV-200 family of Olympus systems that combine phased array, conventional UT, and TOFD technologies for a complete turnkey solution for code based inspections compliant to ASME, API, AWS, and similar procedures. The WeldROVER PV-200 system is designed and developed specifically to comply with these requirements. It is the only phased array system on the market today that can demonstrate a full calibration of every focal law on every channel for: time-of-flight, sensitivity (ACG as defined by ASME), TCG\DAC, and velocity.

The WeldROVER itself is a small, versatile, and easy to operate one-axis encoded motorized scanner. The scanner is operated using a two-button remote control and speed selection switch. It operates at steady speed from 5 mm/s to 50 mm/s in order to achieve a more stable inspection than with manual scanners. Data acquisition is done with either an OmniScan MXU for direct acquisition or a TomoScan FOCUS LT for computer-based acquisition.

Any Olympus UT or PA instrument with an encoder input is compatible with the WeldROVER and requires no programming besides entering the encoder information. Additionally, standard OmniScan or TomoView software is used. No two-way communication between the scanner and instrument is required. The scanner is completely controlled from the WeldROVER remote controller.
