Q1: What is a flaw detector?
A1: A flaw detector is a device used to identify defects or imperfections in materials, structures, or components. It employs various non-destructive testing (NDT) techniques, such as ultrasound, eddy current, X-rays, or magnetic particle testing, to detect cracks, voids, or other irregularities. These methods help assess the internal and surface condition of materials, ensuring their quality and safety. Flaw detectors are widely used in industries like manufacturing, aerospace, and construction to improve product reliability and lifespan.

Q2: How does a flaw detector work?
A2: A flaw detector works by using non-destructive testing (NDT) techniques to inspect materials for internal or surface defects. For example, in ultrasonic testing, the device emits high-frequency sound waves that travel through the material. If there’s a flaw, the waves will bounce back, and the detector measures the time it takes for the sound to return, indicating the size and location of the defect. In other methods, like eddy current testing, electromagnetic fields are used to detect irregularities. The data collected helps technicians identify weaknesses without damaging the material.

Q3: What is the magnetic particle inspection process? 
A3: The magnetic particle inspection (MPI) process is a non-destructive testing method used to detect surface and near-surface defects in ferromagnetic materials. The process involves applying a magnetic field to the object being tested, typically using a yoke or coil. Next, magnetic particles (either in dry or liquid form) are applied to the surface. These particles are attracted to areas where the magnetic field is disrupted by defects such as cracks or voids. The defects are revealed as visible indications in the magnetic particle pattern, allowing for easy identification. After inspection, the particles are cleaned off, and the object is evaluated for any flaws. This method is quick, reliable, and effective for identifying surface defects that could affect the integrity of the material.

Tips: Precautions for using the multi-function magnetic powder flaw detector

1. Working Cycle of the Instrument: It is recommended that for long continuous operations, the magnetization time should be ≤ 3 seconds, and the interval time should be ≥ 5 seconds.
2. Before use, check if the supply voltage matches the instrument's requirements. If the voltage is too high or too low, it may damage the instrument or affect the flaw detection results.
3. During use, ensure that the probe's end face maintains good contact with the workpiece before pressing the magnetization switch for optimal magnetization effect.
4. Although the instrument has excellent no-load overcurrent protection circuits, try to avoid no-load operation to reduce unnecessary temperature rise.
5. The magnetic particle flaw detection gauge can work continuously. If overheating occurs, stop using it, investigate the cause, and only resume operation once the issue is resolved.
6. The flaw detection equipment and its accessories should be used or stored in clean, dry, and non-corrosive environments.
7. When repairing the instrument, be aware of the high voltage risks inside.
8. Do not switch off the power supply when pressing the magnetization switch.
9. The detector’s casing must be reliably grounded.
10. In case of circuit malfunctions that cannot be repaired, please return the instrument for repair.
