Computed Radiography exposure experiments on welded plate sections
were performed to demonstrate that the requirements for pressure vessels weld
inspection according to EN1435 or EN14784-2 class B can be achieved. The
representative comparative studies of the image qualities were performed with
standardized image quality indicators and image evaluation procedures on both film
and digital radiographs. Recommendations for weld inspections with CR systems
are drawn from the results. It is demonstrated that present CR systems can be used
for weld inspection and produce images with testing class B if the selected X-ray
tube voltage is reduced compared with the max. voltage of EN 14784-2 and set
equivalent to maximum X-ray voltage values for steel as defined in the radioscopic
standard EN 13068-3. The work was part of the European 'Filmfree' Project
promoted during the 6th framework.
