火车、轮船、高压容器,各种金属,非金属器件,为了保证使用安全,在制造中常用X光对产品的材料、加工质量进行严格的检验。一台火车锅炉要照几十张片子,目前全部都由人工手动操作。为了不受X光的侵害,操作者要在有铅板防护的室内工作,室内看不到现场,一条环缝来回要跑二、三十趟,对转胎的角度、片子的位置、距离,每次操作都得准确无误,否则不是有重影就是出现漏照。在底片上发现有裂纹、砂眼或漏 Trains, ships, high-pressure vessels, all kinds of metal, non-metallic devices, in order to ensure the safety of the use of X-ray in the manufacture of the product materials, processing quality strictly tested. A train boiler according to dozens of films, at present all by manual operation. In order not to be X-ray damage, the operator should work indoors with lead plate protection, the indoor can not see the scene, a loop back and forth to run two or three times, the tire angle, the film’s position, distance, Each operation must be accurate, otherwise there is not ghosting is a leak. Found in the film cracks, trachoma or leakage
