Tube Voltage Effect on Scattering Ratio in Radiographic Testing for Plate Butt Welds

In order to analyze the voltage effect on scattering ratio in radiographic testing for plate butt welds, so as to better guarantee the image quality of film, in this paper, the variation of scattering ratio is experimented by changing the voltage under the condition of other parameters being invariant. The results show that the scattering ratio decreases with the increase of the tube voltage when the parameters such as tube current, exposure time and focal length are fixed. The experiment provides a reference for the selection of tube voltage in the radiographic testing for plate butt welds.
