一、目的本条例目的是为了帮助探伤人员正确掌握磁粉探伤技术要点及操作方法,以合理地应用和充分发挥磁粉探样在生产检验中的作用。本条例适用于本部各企业及设计,研究单位。上述各单位在进行磁粉探伤时均应遵照本条例制订具体的操作规程。二、磁粉探伤应用范围 1.磁粉探伤主要用来检查铁磁性材料、制品或半制品的表面及近表面裂缝、发纹和较大夹杂等。 2.奥氏体钢或其他非磁性材料所制零件不能用磁粉法检查。
First, the purpose of the purpose of this Ordinance is to help inspectors correctly grasp the main points of magnetic particle inspection techniques and methods of operation, in order to reasonably apply and give full play to the role of magnetic particle exploration in the production test. This Ordinance applies to all enterprises and design, research institutes. The above units in the magnetic particle inspection should be in accordance with the Ordinance to develop specific operating procedures. Second, the application of magnetic particle inspection 1. Magnetic particle inspection is mainly used to check the ferromagnetic materials, products or semi-finished products near the surface cracks, hair lines and larger inclusions. 2. Austenitic steel or other non-magnetic materials manufactured parts can not be checked by the magnetic particle method.
