Ultrasonic Side-Looker for Rail Head Flaw Detection

摘要: An ultrasonic rail flaw detection system and technique are described for the of flaws in sides heads. transducer (20) is oriented, sized, located so as to produce an beam (50) within head (48) whereby at least a portion will intersect lower side corner independent curvature running surface amount wear. The presence premature reflections or absence can be used detect such vertical fractures head. side-looker oriented that lies 45 degrees 75 normal surface, its beams from other transducers do not interfere with each other.
