摘要： An apparatus is provided for x-ray inspection of a pipeline girth weld. This comprises a directional x-ray source 5 which is insertable into a pipeline section and is rotatable within the pipeline. Means are provided to align the directional x-ray source with an external x-ray detector such that both may be rotated through 360 degrees substantially coaxially with the pipeline section. Means for sampling the data detected by the x-ray detector are provided so that it may be further analyzed.

摘要： An apparatus is provided for external inspection of a pipeline circumferential weld. This comprises a radiation source (5) and radiation detector (3). Both units are controllably movable around a drive band or track (7) which is fitted around the circumferential weld. To align the source with the detector the source and detector are moved with respect to each other clockwise and anticlockwise around an initial position while sampling the radiation detected at a number of positions. A position of maximum strength of the radiation signal detected can then be determined such that the center point of the radiation source may be located. The source and detector are then substantially aligned with each other and means are provided to move the source and detector circumferentially around the weld while remaining substantially in alignment.
摘要翻译：提供了一种用于外部检查管道周向焊缝的装置。这包括辐射源（5）和辐射探测器（3）。两个单元可围绕围绕周向焊缝的驱动带或轨道（7）可控地移动。为了使源与检测器对准，源和检测器相对于彼此顺时针和逆时针方向相对于初始位置移动，同时对在多个位置处检测到的辐射进行采样。然后可以确定检测到的辐射信号的最大强度的位置，使得辐射源的中心点可以被定位。源和检测器然后基本上彼此对准，并且提供装置以使源和检测器周向地围绕焊缝移动，同时保持基本上对准。
