Problems solved by technology

[0002] When performing real-time imaging detection on workpieces, since the existing X-ray flaw detectors do not have radiation dose detection and control, users cannot know the radiation dose rate and cumulative dose when using X-ray flaw detectors to detect workpieces. The radiation dose of the X-ray flaw detector can be estimated by observing the exposure parameters (such as kV, mA, and exposure time, etc.). Whenever the material, thickness, and filming focal length of the workpiece change, the exposure parameters and To obtain the required radiation dose, it is time-consuming and labor-intensive, as well as a waste of materials

Abstract

A method for controlling X-ray crack detector includes adding X-ray dosage detection-control unit on existing X-ray crack detector to let said detector have detection-control function of radiation dosage for displaying dosage rate and accumulation dosage of radiation in real time, enabling to convert accumulation dosage to be blackness value of film for controlling exposure parameters so as to have optimum imaging-result.

Description

technical field [0001] The invention relates to a radiation dose control method and a detection control device of an X-ray flaw detector. Background technique [0002] When performing real-time imaging detection on workpieces, since the existing X-ray flaw detectors do not have radiation dose detection and control, users cannot know the radiation dose rate and cumulative dose when using X-ray flaw detectors to detect workpieces. The radiation dose of the X-ray flaw detector can be estimated by observing the exposure parameters (such as kV, mA, and exposure time, etc.). Whenever the material, thickness, and filming focal length of the workpiece change, the exposure parameters and The required radiation dose can only be obtained by filming, which is time-consuming and labor-intensive, as well as a waste of materials. Contents of the invention [0003] According to the defects existing in the existing X-ray flaw detector, the invention proposes a control method for the X-ray...
