盘管对接焊缝射线检测

Butt-welded Joints RT Inspection

采用小管径对接焊接接头的γ射线照相技术。按照JB/T4730.2-2005标准规定,根据工件特点和检验要求,选择适当的Se75-射线检验方法。用此种方法透照所要检验的管对接焊缝,用固定板固定射源很方便,只要将所要透照的管对接焊缝接头找出最佳偏移距离,将γ源置于偏移距离处,即可固定射源方便又快捷地进行检验。

Small diameter butt - welding joints of γ- ray photography are used. As per B/T4730. 2 -2005 standards, according to the work piece characteristics and inspection requirements, the appro- priate Se75 - ray inspection methods are selected. It is very convenient to use this method to test the butt -welding joints, and to use a fixed plate to fix radiation source. As long as one points the γ source at butt - welding joints to find the best offset distance, the radiation source can be fixed easily and tested quickly.
