摘要
焊接是换料水箱重要的制造工艺方法,焊接质量的好坏对换料水箱的质量起着重要作用,因此,如何保证换料水箱焊接质量是保证换料水箱的质量关键。分析00Cr19Ni10(304L)材料的焊接特点、换料水箱焊接过程中的难点、影响焊接质量的因素;总结换料水箱的焊接原则、焊接注意事项,并从焊接事前控制、焊接质量的事中与事后控制方面入手,阐述焊接质量控制措施。为后续核电厂贮罐焊接质量控制提供参考。
Welding is an important fabrication process of in-containment refueling water storage tank(IRWST), and welding quality plays an very important role in controlling the quality of the IRWST, so how to ensure the welding quality is the key to the overall quality of IRWST. In this paper, the welding characteristics of steel 00Cr19Ni10(304L), difficulties in the welding process of IRWST and factors affecting welding quality are analyzed, and the welding principle and matters need attention are also summarized. And the welding quality control measures are described in detail from the aspects of the preweld control, in-process control and postweld control. This paper could be a reference for the welding quality control of storage tanks of nuclear power plants in the future.
