    • The present invention relates to method for ultrasonic inspection of a test object, comprising the steps of defining a coordinate system of the test object based on at least a first, a second and a third spatially separated position at a surface of the test object; selecting, relative to the coordinate system of the test object, at least one position of a test area of the test object; positioning at least one ultrasonic measuring device at the at least one position within the test area; transmitting, by means of the at least one ultrasonic measuring device, an ultrasonic wave pattern into the test object; receiving an ultrasonic wave pattern signal; acquiring an ultrasonic reference wave pattern signal for a reference area of a reference object, the reference area provided with at least one ultrasonic measuring device having a position within a coordinate system of the reference object corresponding to the at least one position of the test area within the coordinate system of the test object; and comparing the received ultrasonic wave pattern signal from the test object with the acquired ultrasonic reference wave pattern signal of the reference object for detecting a defect in the test object.
    • 本发明涉及用于测试对象的超声波检查的方法,该方法包括以下步骤:基于测试对象的表面处的至少第一,第二和第三空间分离位置定义测试对象的坐标系; 相对于测试对象的坐标系选择测试对象的测试区域的至少一个位置; 将至少一个超声测量装置定位在所述测试区域内的所述至少一个位置处; 借助于所述至少一个超声测量装置将超声波图案传输到所述测试对象中; 接收超声波图案信号; 获取用于参考物体的参考区域的超声波参考波形图信号,所述参考区域设置有至少一个超声波测量装置,所述超声波测量装置具有在所述参考物体的与所述测试区域的所述至少一个位置相对应的坐标系内的位置 测试对象的坐标系; 以及将来自测试对象的接收到的超声波图案信号与所获取的参考对象的超声波参考波形图信号进行比较,以检测测试对象中的缺陷。
