Application of magnetic particle flaw detection, ultrasonic flaw detection and radiographic flaw detection

1. Magnetic particle inspection: it is mainly used for the inspection of metal surface cracks. The magnetic field formed by current forms NS pole on the surface of metal cracks, and the magnetic particles adhere to form crack lines, which is suitable for the inspection of weld surface cracks; 2. Ultrasonic flaw detection: It is more sensitive and convenient than X-ray when checking the internal cracks of welds and plates. 3. X-ray flaw detection is more sensitive than ultrasonic detection when checking the internal pores and slag inclusions of welds and plates.
