    • A rail section weld inspection device [1000] is described for inspecting a rail [10] for internal defects [19,21]. A central ultrasonic (US) probe [1330] transmits at least one US beam [B] through the rail [10] and receiving a reflected signal. At least one angled US probe [1310] transmits at least one US beam [A1-A5] through the rail [10] at an oblique angle at least partially covering the same region as the central probe [1330]. An encoder [1380] identifies the location of the US probes [1330] and [1310] along the rail [10] and pairs the locations of the probes with the signals received. The Calculation device [1500] receives the signals from the US probes and uses their different views to create an image of the flaws within the rail [10].
    • 描述了用于检查轨道[10]内部缺陷的轨道部分焊接检查装置[1000] [19,21]。 中央超声波(US)探头通过轨道[10]传送至少一个US波束[B]并接收反射信号。 至少一个有角度的US探头以至少部分地覆盖与中心探针相同的区域的倾斜角度透射至少一个US光束[A1-A5]穿过轨道[10]。 编码器沿着轨道[10]识别美国探测器和[1310]的位置,并将探测器的位置与所接收的信号进行配对。 计算装置[1500]接收来自美国探测器的信号,并使用它们的不同视图来创建轨道内的缺陷图像[10]。
