The invention relates to a system and a method for detecting the babbitt metal bonding quality of a bearing bush, and belongs to the field of nondestructive detection of defects of metal parts of a hydropower station. The problems that the blind area is large, the ultrasonic echo resolution of the tire-falling is low, and the tire-falling phenomenon below half of the area of a probe wafer cannot be effectively detected can be effectively solved. Imaging detection can be carried out, and the bearing bush tire release condition can be effectively and visually displayed. 本发明涉及一种检测轴瓦巴氏合金结合质量的系统和方法，属于水电站金属部件缺陷无损检测领域，该方法运用全聚焦相控阵检测检测技术对水电站轴瓦巴氏合金结合层质量进行检测，可以克服盲区大、脱胎超声波回波分辨率底及能够有效解决探头晶片面积一半以下的脱胎无法有效检出的问题。而且能够进行成像检测，有效、直观显示出轴瓦脱胎情况。
