Abstract：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.
