Non-destructive Eddy Current Flaw Detector

The non-destructive eddy current flaw detector operates based on the principle of electromagnetic induction, inducing eddy currents in conductive materials through an alternating magnetic field to detect surface or near-surface defects. It is used to identify discontinuities such as cracks and corrosion, making it suitable for the online inspection of metal pipes, rods, and aerospace components.
Selection
When selecting, consider material conductivity, detection depth, and defect types to match probe frequency and size. Focus on equipment sensitivity, environmental adaptability, and ease of operation to ensure compliance with industry standard testing requirements.
