Flushing Flaw-detection probe for steel track

The utility model relates to a flushing flaw detection probe for rails, which is a double-wafer probe matched with a 518 type ultrasonic wave flaw detector. The utility model comprises a base and a probe in the base, and the incident angle of the double wafers and a normal on a triangular glass cutter slope in the probe is 25-40 DEG and 32-45 DEG. One other slope is a wave-shaped sound absorption surface, the ring number of the sound absorption impedance coil on the double wafers and a reversed connecting lead is 10-20, the wafer frequency is 5 M, and the sensitivity can reach 59 db. Therefore, the utility model has stable and reliable flaw detection, simple structure, easy fabrication and low cost.
