磁粉探伤是直接观察工件表面磁痕显示的一种无损检测方法,磁痕是由磁粉堆积而成的,如果现场照明不好,势必影响观察,影响磁粉检测的可靠性。
Magnetic particle inspection is a non-destructive testing method that directly observes the magnetic marks on the surface of a workpiece. Magnetic marks are formed by stacking magnetic powder. If the on-site lighting is not good, it will inevitably affect the observation and affect the reliability of the magnetic particle inspection.
