对于钢轨内部伤损的检测,可以采用超声、射线探伤等方法。但在野外作业,最简便、有效、快速的方法,当推超声波探伤。西德、日本、美国、苏联等,都有专用的铁路钢轨探伤车。除了有手推小车外,还有火车头牵引的大型探伤列车。使用探伤车后,钢轨内部伤损可以预先发现而做到预先更 For the detection of rail internal injuries, you can use ultrasound, ray inspection and other methods. But the easiest, most effective and fast way to work in the field when pushing ultrasonic flaw detection. West Germany, Japan, the United States, the Soviet Union, etc., have a dedicated railway rail detection car. In addition to hand-push the car, there are large-scale trains trains trains. After using the test car, the internal rail damage can be found in advance to do more
