摘要：X-ray Digital imaging is an innovative method of metal fusion welding quality evaluation. To improve the accuracy, the digital imaging sensitivity must be increased by studying the optimal radioactive parameters. At first, the basic elements, inherent characteristics and imaging principle have been analysed systematically. Secondly, the optimization method of sampling rate, stacking frames, focal length, cube voltage and current have been studied based on the phisical characteristic of FPD(Flat Panel Detector). At last, the method has been verified upon two platforms. The experimental results from different systems proved correctness and applicability.
