A Study on Ultrasonic Detection of Flaws in Welds of Rails
, 1999 During manufacture and in service, various defects might emergence in rails. Some defects are volume ones, and others are planar ones, like facula, greyness, non-welded together and fatigue crack. plane defects are very dangerous. They not only reduce the effective section of rail, but also bring on stress concentration.
