1.SummaryIn this experiment, the main objective was using two methods of nondestructive testing on the metal specimens to determine their flaws and cracks. The first of the methods was the Magnetic Particle method that involves dusting the surface of the metal specimen with iron particles, either dry or suspended in a liquid, which in this case was dry. After application to the surface, a magnetic tool induced a magnetic field to shift the particles into cracks, exposing the metal specimen flaws and cracks. The second method was called the Liquid Penetrant method that involved using certain aerosol cans containing certain liquid ingredients to act upon the metal specimens, to show their imperfections around welds and cracks in the metal itself.
