... media that have different acoustic velocities. Depending on the mode of particle motion, ultrasonic waves are classified as longitudinal waves, vertically and horizontally polarized shear and transverse waves, surface waves, Lamb waves, etc. Four wave modes are described in the following paragraphs...

Magnetic particle inspection offers the same visual aid in the nondestructive inspection of bars as it does for castings, forgings, or machined products. The method is used for detecting seams, cracks, and other surface...

.... The probe, moving through the diverted flux, generates a signal roughly proportional to the size of the flaw. On a longitudinal welded seam, an electromagnet with pole pieces on each side of the weld can be used to magnetize the weld area, with flux passing transversely across the seam. The magnetic flux...

The method is based on the fact that when a material or part being tested is magnetized, discontinuities that lie in a direction generally transverse to the direction of the magnetic field cause a leakage field to form at and above the part surface. The presence of the leakage field...
