TWI’s NDT Group has extended the capability of its Cambridge facility with the addition of Digital Radiography (DR) to its traditional wet film radiography offering. The benefits of DR include, shorter inspection times, simplified image processing and higher quality images.
The recently installed DR equipment includes a high resolution Digital Detector Array (DDA) with a resolution of 75 microns, housed in an exposure bay that can accommodate components up to 5m long, 2m wide and 2.6m in height. It has been specifically designed for industry sectors that require high resolution digital radiographs that meet stringent industry standards, such as the aerospace sector.
To complement the DDA offering, TWI also provides Computed Radiography (CR) as an alternative digital radiography solution. CR uses high resolution flexible imaging plates that can be easily manipulated to cater for components with more complex shapes.
