小径管γ源透照椭圆成像工装的应用

Application of small tube Gamma source elliptic imaging frock

通过对小径管探伤方法的研究,发现只有准确固定源头的位置,才能降低废片率,而探伤人员在现场无法准确固定源头的位置,只能通过工装来实现。而本论文据此改进,制作了既能准确固定源头的位置,并能严格控制透照焦距和椭圆成像位移距离的装置。

The research on small diameter pipe detection indicates that only when the location of the source is determined the rate of waste can be reduced,while the flaw detection cannot be fixed at the site,frock is necessary in this operation consequently. This article provides upgrading device which is made to locate accurate fixed source and be able to strictly control irradiating focal length and elliptical imaging displacement distance.
