Experiments show that the detection problem of the internal defects of the axle head part of the axle bridge casting product can be effectively solved by adopting an ultrasonic detection method. Therefore, it is necessary to produce a calibration block for ultrasonic testing of axle bridge casting products for (a group of) low-floor trams, and to perform testing and determination of the axle bridge casting products according to the transmission of the equivalent of artificial defects on the calibration block.
