摘　　要：随着焊接技术的广泛应用,焊接接头冷裂纹的形成也备受关注。焊缝中的扩散氢是导致焊缝区产生氢致裂纹的重要原因之一。详细综述了近年来焊缝金属中扩散氢的来源、产生和扩散氢质量分数测定方法的研究进展,总结了影响扩散氢质量分数的有关因素。着重分析了氢在焊接接头的动态扩散行为,对扩散氢的危害和预防措施进行总结,并对相关研究存在的问题和进一步的研究方向进行概括。With the wide application of welding,there is a growing concern about the cold cracks of welded joints. The diffusible hydrogen in steel weldments is one of the main reasons these lead to hydrogen assisted cracking. In this article,the source and production of diffusible hydrogen were summarized. Then this paper reviewed the measurement of diffusible hydrogen and summarized the reasons for affecting diffusible hydrogen content. And the dynamic and effect of hydrogen were analyzed emphatically. Subsequently,it introduced perniciousness and prevention of diffusible hydrogen. At last we pointed out the problems in research of diffusible hydrogen and look forward to the future of the research.
