Abstract：The end-corner reflection test system is built basing on Z-scan ultrasonic detector, standards and reference blocks,as well as UltraVision ultrasonic signal acquisition and analysis software. Respectively, the end-corner reflection of 45°、60°and 70°Ultrasonic transducers is tested. First, all reflection echo signal are sampled and analysed, and then the end-corner reflection echo signals is isolated basing on ultrasonic propagation law and the end-corner reflection waves mode conversion law. The relative reflectance of the above signal is computed at last. Test results show that 45 °transverse wave transducer end-corner reflection close to the total reflection. The clutter from the end-corner reflection of longitudinal wave transducer is more than the transverse wave transducer.
