车轴不解体超声波探伤法在任何场合均可以对车轴进行不解体探伤及监视“病轴”裂纹的发展。这种探伤法1977年由铁科院研试成功,是机务段较理想的一种快速检查车轴裂纹方法。1972年我段对6Y_2型电力机车部分车轴的非齿侧轮座进行过超声波探伤,当时发现轮座内侧距边缘10～15毫米处近90％的轴产生不同深度的裂纹,退轴后电磁探伤验证无误。当时我们采用30°斜探头在抱轴颈处进行横波探伤,这种探伤法必须解体转向架和轮对,其作业过
Axle does not disintegrate Ultrasonic testing can be carried out in any case on the axle without disintegration flaw detection and monitoring of “sick axis” crack development. This test method was successfully tested by the ASTRI in 1977 and is an ideal way to check the axle cracks in the locomotive depot. In 1972, I conducted ultrasonic testing on the non-tooth-side wheel base of 6Y_2 electric locomotive axles. At that time, it was found that there were cracks of different depths on the axis of 10-15 mm from the edge of the wheel seat. Verification is correct. At that time, we used 30 ° oblique probe to carry out transverse wave flaw detection. This method of flaw detection must disassemble the bogie and the wheelset.
