在工业生产中应用无损探伤的主要目的,是能在不损坏工件或原材料的前提下,发现其中的缺陷,以保证使用的可靠性,并根据缺陷的性质,改进生产工艺,使之完善,以减少废品率,降低生产成本。因此,必须有一个切实可行的探伤规范和正确的判别缺陷的方法,做到既不漏检,也不误判。怎样来正确识别缺陷的性质呢?我们遵照伟大领袖毛主席关于“一个正确的认识,往往需要经过由物质到精神,由精神到物质,即由实践到认识,由认识到实践这样多次的反复,才能够完成”的教导,对经过磁粉探伤,发现
The main purpose of applying NDT in industrial production is to discover the defects therein without damaging the workpieces or raw materials so as to ensure the reliability of the use and to improve and perfect the production process according to the nature of the defects Reduce the rejection rate, reduce production costs. Therefore, there must be a practical flaw detection norms and the correct method of identifying defects, so as not to miss seizure, or misjudgment. How to Correctly Identify the Nature of Defects? We follow Chairman Mao, the great leader, that “a correct understanding often requires going through a process of changing from substance to spirit, from spirit to substance, from practice to understanding, , To be able to complete ”the teaching, after magnetic particle inspection, found
