摘要
焊接生产过程中,由于各种原因,在焊接结构中会产生不同类型的缺陷,直接影响焊接质量。对国内外焊接缺陷X射线自动检测相关关键技术的研究现状给予系统的论述,包括图像增强、图像分割和模式识别,最后对这一检测技术进行了展望。
In the process of welding,different kinds of reason can lead to different types of defect in weld structure,which will directly influence the quality of the welding structure.In this paper, the present research situation of the relevant key technologies of automatic detection of weld defect by radiography in domestic and oversea is discussed and prospected, including image enhancement, image partition, and pattern recognition.
