Ultrasonic Inspection of Surface Defects on Cold Rolled Steel Strip
DENKI-SEIKO[ELECTRIC FURNACE STEEL], 1971 Utilizing of ultrasonic method was studied for inspecting of surface defects on cold rolled steel strip.When the ultrasonic wave is projected in the water against surface of steel strip keeping proper projecting angle, the total reflection occures on the surface.But there occurs irregular reflection on parts where there are any defects or flaws and ...

Scanning laser source and scanning laser detection techniques for different surface crack geometries [PDF]
, 2012 Standard test samples typically contain simulated defects such as slots machined normal to the surface. However, real defects will not always propagate in this manner; for example, rolling contact fatigue on rails propagates at around 25º to the surface,
