在X射线拍片时,欲获得黑度基本一致的X射线底片,除曝光条件合适外,还与主射线束是否垂直于透照部位的正切平而有关,否则X射线底片两端容易产生明显的黑度不均匀和使焊缝在底片上的影象变形,影响射线底片的透照质量。为此我们自制了一个检测横放的圆筒形容器的X射线探伤机支架,它既能满足探伤要求又能相应缩短探伤辅助时间。 In the X-ray film, to obtain a substantially uniform black X-ray film, in addition to the appropriate exposure conditions, but also with the main beam is perpendicular to the transillumination site tangent level and related, or X-ray film at both ends of the prone to obvious Uneven blackness and the image of the weld on the film deformation, affecting the radiographic quality of the film. For this purpose, we made a self-made X-ray inspection machine stand for inspecting horizontal cylindrical containers, which not only can meet the inspection requirements but also shorten the testing auxiliary time.
