It is common to see the term ‘crack-free’ used in product specifications and although the concept may be simple to understand, it is too wide and ambiguous.
Testing magnetic particles not only involves crack detection, but also allows us to locate a wide range of defects (The micro values mentioned below are the metallographic results of inconsistencies or defects in real Magnetic Particle tests).
