射线探伤是承压设备无损检测中五大常规检验方法之一,在锅炉、压力容器、压力管道制造、检修行业得到广泛应用。X射线机作为一种常用的检测设备,在使用的过程中会因为相关元器件的消耗、老化而使原本适用的曝光曲线不再适用。而曝光曲线是描述在特定的条件下(胶片、增感屏、焦距、黑度、射源和暗室处理等一定),工件厚度与所需曝光参数之间的关系曲线。在射线照相检验中,利用曝光曲线可以迅
Radiowave detection is one of the five routine test methods for non-destructive testing of pressure equipment. It is widely used in the manufacture of boilers, pressure vessels and pressure pipelines and overhauls. X-ray machine as a commonly used testing equipment, in the course of the use of related components due to consumption, aging so that the original exposure curve is no longer applicable. The exposure curve is to describe the relationship between the thickness of the workpiece and the desired exposure parameters under certain conditions (film, intensifier screen, focal length, blackness, source and darkroom handling, etc.). In radiographic examination, the use of exposure curve can be quickly
