The Principle of Magnetic Particle Inspection:

The principle of magnetic particle inspection plays a crucial role in the functionality of the Non-intrusive Pig Signal Indicator. When magnetizing a magnetically conductive metal workpiece to saturation, defects such as cracks, slag inclusions, or pores disrupt the passage of magnetic lines of force, resulting in magnetic flux leakage. By spraying magnetic powder or a magnetic powder suspension on the inspected workpiece’s surface, the leakage magnetic field attracts the magnetic particles, clearly highlighting the presence of defects.

The indicator’s detection methods can be categorized into two types:

  1. Additive Method (Continuous Method): In this technique, magnetic powder is sprayed onto the tested workpiece while simultaneously applying magnetization.It is particularly effective for materials with low coercivity and remanence, such as mild steel. The additive method offers higher detection sensitivity with a lower magnetizing current, although it may have lower inspection efficiency and require more complex operations.
  2. Residual Magnetism Method: In this method, the residual magnetism of the magnetized workpiece is utilized for inspection. After magnetization, the magnetizing current can be disconnected, and then magnetic powder or a magnetic suspension is sprayed onto the surface. The advantage of this method is its simplicity and high inspection efficiency. However, the residual magnetism method necessitates a higher magnetizing current, approximately three times greater than that used in the additive method. The material being inspected must possess high coercivity and remanence to ensure sufficient residual magnetism for effective inspection. Operators must also exercise caution when using alternating current or half-wave rectification as the magnetizing current.
