介绍了锅炉受热面管焊缝常见缺陷及射线检测定性的影像分析要点 ,给出了常见焊缝缺陷的一般分布规律及形成原因 ,对于现场进行射线检测缺陷的识别和正确评定 ,不仅提供了理论上的指导 ,同时更为准确地鉴别受热面管焊缝缺陷和进一步保证受热面管焊缝的焊接质量提供了充分的依据。
This paper introduces the main points of the image analysis of the welding defects of the heating surface tube of the boiler and the qualitative analysis of the radiation detection. It gives the general distribution rules and reasons of the common weld defects. The identification and correct assessment of the defects of the radiation detection on the site not only provide the theory On the guidance, at the same time more accurately identify the heating surface of the weld defects and to further ensure the heating surface weld quality welding provides a sufficient basis.
