description: In this work the ways of hydrogen penetration and interaction of hydrogen with metal is described. Explained distribution of hydrogen in weld and heat affected zone. Dependence of hydrogen concentrations in metals on content of it in the atmosphere or into coated electrodes is adduced. The most known methods of diffusible hydrogen determining are described and added compering of vacuum analysis method with liquidmanometer up to method with using of special device for diffus-ible hydrogen determining.,Content of diffusive hydrogen in experimental deposited metal made with use of OK 74.70 electrodes by Swedish firm ESAB. Description of the experiment,included: description of specimen preparation,welding process,processing of speci-men after welding and analysis of the diffusible hydrogen content.
