In a magnetic particle inspection, a flaw that is perpendicular to the magnetic field flux lines
generally causes a.... - ANS ✔✔Large disruption in the magnetic field.
a double butt joint weld should have: - ANS ✔✔100% penetration
What is residual magnetization? - ANS ✔✔Magnetism left in steel after heat treatment
Dye penetrant is used on what type of materials? - ANS ✔✔non-porous
To detect a minute crack using dye penetrant it usually requires - ANS ✔✔A longer than normal
