General This procedure is applied to the magic particle examination of ferromagic materials and welds for ASME Code items. The magic particle examination method is suitable for detecting cracks and other discontinuities on or near the surface in ferromagic materials. This procedure is applied to wet continuous magization by yoke, which shall only be applied to detect discontinuities that are open to the surface of the part. This procedure shall be demonstrated to the satisfaction of the AI prior to implementation. 2. Personnel The NDE personnel who engage in magic particle examination shall be qualified and certified according to ****** Co.,Ltd.’s “Written Practice for NDE Personnel Training, Examination, Qualification amp。 Certification”(No.:QCD011). 3. Description of Method In principle, the magic particle examination method involves magizing an area to be examined, and applying ferromagic particles to the surface. The particles will form patterms on the surface where cracks or other discontinuties cause distortions in the normal magic field. These patterns are usually characteristic of the type of discontinuity that is detected. The sensitivity of the magic particle examination is greatest for surface discontinuities and diminishes rapidly with increasing depth of discontinuities below the surface. Therefore, this method can only be used for detecting the discontinuities on or near the surface of the material or parts to be tested. 4. Magization Equipment and Calibration The MT equipment to be used is Yoke, with Type CDX4. Calibration of Equipment Frequency of calibration: Each
