The inspection of steel welds is a requirement in many safety critical applications, with X-rays offering an excellent visual aid in quality monitoring of such parts. In order to penetrate the steel and the weld, high energy X-rays are usually required though, depending on the material's thickness and the length of material the X-ray beams must traverse. The high beam energies can seriously degrade the X-ray detectors' life expectancy and image quality, so in order to ensure consistent image quality traditional X-ray film has been used, in spite of its drawbacks regarding the ecological impact of the chemical process and the significant efforts involved if archives of the welds must be maintained. This paper presents an alternative solution to the traditional photochemical archival approach using a custom X-ray detector developed specifically for the inspection of welded seams.

The results of automatic X-ray inspection of cast parts rely heavily on the quality of the imaging components. Flat panel detectors suffer from a number of flaws, the most serious being long-term stability and image quality. This paper presents a new X-ray detector design which can increase defect detection quality, cost efficiency and long term stability of an industrial automatic X-ray inspection system.
