1 问:如何理解磁粉探伤中磁场、感应磁场和漏磁场的概念?答:磁粉探伤工艺过程:将铁磁性材料的工件置于磁场中磁化,工件上获得比磁场大数百倍以上的感应磁场。当工件上感应磁场达到探伤灵敏度要求的经
1 Q: How to understand the concept of magnetic field, induced magnetic field and magnetic leakage field in magnetic particle inspection? A: The magnetic particle inspection process: the workpiece is placed in the magnetic field of magnetized magnetic material, the workpiece is greater than the magnetic field hundreds of times greater than the induced magnetic field . When the workpiece magnetic field to detect the sensitivity requirements of the experience
