摘要: 介绍了金属蜂窝钎焊件生产制造过程中的实时成像检测。传统射线照相技术受限于管径及射线束角度,透照有效区域小,大型蜂窝结构件检测效率低;同时还会发生由于工件厚度变化致使芯格影像变形的问题,影响检测结果的判断。运用实时成像技术对蜂窝结构件移动扫描检测,有效地解决了上述问题,同时使用分辨率测试卡,保障了系统的分辨力,获得了满意结果。Abstract: This paper introduces the real-time imaging detection technology during the manufacturing process of brazing metal honeycomb. Traditional radiography is limited by the diameter-ray beam angle and the effective areas of Tran-illumination are small, hence the detection of large-scale honeycomb structure are less efficient; Meanwhile, the imaging deformation of the core grid due to the thickness change of the work piece might occur. The paper uses the real-time imaging technology to dynamically scan the honeycomb structure and to detect defects, and it is proven effective to solve the above problems. At the same time, a satisfactory result was obtained based on the system resolution provided by the resolution test meter.
