磁粉聚集在探伤零件上,究属真假缺陷和缺陷性质如何,不仅要懂得各类缺陷特征,而且需了解工艺过程,加工方法和对假缺陷有一定分析能力。准确地辩别缺陷是磁性探伤工作中较重要和较复杂工作之一。要做好这一工作,不仅要思想集中地检查,而且在实际工作中对可疑缺陷经常进行分析研究,不断积累经验,切实掌握好缺陷判断技术,才能达到准确判断缺陷和全面发现缺陷目的。
Magnetic particles gathered in the testing parts, belong to true and false defects and the nature of defects, not only to understand the characteristics of various types of defects, but also need to understand the process, processing methods and false defects have some ability to analyze. Accurately identify defects is one of the more important and more complex work in magnetic flaw detection. In order to do this work, we should not only conduct a centralized examination of ideology, but also conduct regular analysis and study on suspicious defects in practical work, continuously accumulate experience and master the techniques of defect judgment so as to achieve accurate judgment of defects and comprehensive defects detection.
