4. Magnetic particle inspection
Non-destructive testing by magnetic particle inspection aims to detect surface or underlying defects (figure 3 ).
4.1 Excitation phase analysis
The part is subjected to the action of the magnetic field. There are three important magnetic field parameters to consider:
its nature. The waveform used conditions the penetration of the induction lines into the cross-section of the part. The closer we are to the wave corresponding to the DC field, the deeper we penetrate into the cross-section, and the better we can detect underlying defects. Depending on the system used, various waveforms can be encountered:...
