| Abstract: | The diffusible hydrogen content in the deposited metal using CM-9Cb, R347 and newly-developed T91 electrode was measured respectively through glycerine hydrogen test, and the tendency for hydrogen-induced cracking of the T91 and steel 102 joint welded with different electrodes was investigated by means of electrolytic hydrogen charging and constant-load delayed cracking test, and the critical stress was determined. |
