以AP1000核电工程中CA03结构模块中6mm厚薄板X型坡口对接焊缝为研究对象,因受薄板焊缝高度与母材厚度之比大的因素影响,试验采取八组不同的射线管电压和照相时间进行射线照相,最终通过焊缝胶片的质量评审结果和母材及焊缝的黑度对比总结出一种针对薄板焊缝的射线检测方法。
In the AP1000 nuclear power project CA03 structural module X-groove butt-welded 6mm thick sheet as the research object, due to the sheet metal weld height and the thickness of the base metal ratio of the factors that affect the test to take eight different sets of tube voltage and Photographic time radiography, and finally through the weld film quality assessment results and the base metal and weld blackness summed up a method for the ray detection of sheet metal welds.
