Microfocus Digital Radiography Automatic Detection Technology for ZL205A Alloy Tube Castings

ZL205A合金筒类铸件的缺陷检测采用传统的胶片射线照相。为降低其检测成本并提高效率,采用微焦点射线数字成像自动检测技术,制定检测工艺参数,控制图像质量。通过ZL205A合金筒类铸件微焦点射线数字成像与胶片法检测对比,以及缺陷图像对比,验证了微焦点射线数字成像自动检测与胶片射线照相具有等价性,完全可以替代传统的胶片射线照相,从而极大提高了检测效率,减轻了检测人员工作强度,降低了材料成本。

The detection for the defects of ZL205A alloy tube castings usually adopts conventional film radiography, which exposes some problems such as high material cost and lower detection efficiency. In the present study, the microfocus digital radiography automatic detection technique was utilized, a comparison with the film method was carried out, and their defect images are also presented, to verify that the microfocus digital radiography automatic detection method has equivalence property with the film radiography and can completely replace traditional film radiography. Our experimental results demonstrate that the microfocus digital radiography automatic detection method can significantly improve the detection efficiency, weaken the work intensity of detection workers and reduce material cost.
