The company has developed a laser ultrasonic flaw detection system for train wheels, including: a support carrier whose structure is consistent with the structure of the tested train wheels to fix and support the tested train wheels; A laser generator arranged on one side of the support carrier; The reinforcing medium layer is arranged between the support carrier and the detected train wheel and is fitted with the detected train wheel. The reinforcing medium layer can receive laser and excite ultrasonic wave; A lens system on the same side as the laser generator so that the laser is reflected on the enhancement medium layer through the lens system; The ultrasonic receiving device is arranged around the support carrier. The utility model provides a method for carrying out laser ultrasonic flaw detection on train wheels by using a laser to carry out laser ultrasonic flaw detection on the tested train wheels through an enhanced medium layer, which avoids the damage of train wheels caused by direct contact and improves the ultrasonic conversion rate.
