  • Penetrant Testing to Detect Internal Defects in Castings

    Penetration testing (PT) is also a kind of non-destructive testing. Its basic principle is to use the good permeability and capillary action of colored penetrants or fluorescent penetrants to narrow gaps. After penetration, removal, and imaging treatment, the surface def...
