通过大量工艺试验,较系统地分析了影响钛合金压力容器焊缝X射线照相灵敏度的各个因素。研究结果表明:在诸多因素中,底片黑度、底片对比度、影像不清晰度、颗粒度是影响X射线照相灵敏度的主要因素。在优化探伤工艺后所透照的X射线底片,其灵敏度和清晰度已完全达到了X射线标准。 Through a large number of process tests, the various factors affecting the X-ray radiographic sensitivity of titanium alloy pressure vessel weld were systematically analyzed. The results show that: in many factors, the negative blackness, negative contrast, unsharpness, granularity are the main factors affecting the radiographic sensitivity. The X-ray film, which has been transcribed after the optimization of the inspection process, has fully achieved its X-ray sensitivity and sharpness.
