02:56 Nov-08-2009 Mapping out ID cracks in plate in pipe
When mapping out ID cracks with shearwave ultrasound, does the standard 6dB drop method work? I just read an article that said the main reflector of an ID crack is actually the base of the crack. Well if that is the main reflector, would moving the transducer forward and backward until a 6dB drop was obtained in each direction give the actual throughwall depth of the crack? Or is a more advanced method like crack tip diffraction needed to measure the throughwall depth of the crack?
A larger FOV DDA can reduce the space and volume of the X-ray inspection system on the factory floor
, enable faster scanning times, better throughput and better resolution images at a lower dose. Customers can also save time and money. With these benefits in mind, Varex Imaging has designed a family of large FOV detectors (4343HE, XRD 1611, 4343DX-I, 4343CT) for our industrial imaging customers.
ScanMaster ultrasonic immersion systems are designed for high throughput, multi shift operation in a
n industrial or lab environment. These fully integrated systems provide various scanning configurations and incorporate conventional and phased arrays technologies to support diverse applications, such as inspection of disks, bars, shafts, billets and plates.
All of ScanMaster immersion systems are built from high accuracy scanning frames allowing for scanning of complex parts and include a multi-channel ultrasonic instrument with exceptional performance. The systems are approved by all major manufacturers for C-scan inspection of jet engine forged discs.
Together with a comprehensive set of software modules these flexible series of systems provide the customer with the best price performance solutions.
