| 摘 要： | 用甘油法测定了从日本进口的ＣＭ－９Ｃｂ焊条、国内新研制的Ｔ９１专用焊条以及Ｒ３１７焊条熔敷金属中的扩散氢含量。通过阴极电解渗氢和定载延迟开裂试验，研究了不同焊条焊接时，Ｔ９１／１２Ｃｒ１ＭｏＶ接头的氢致裂纹倾向。试验结果表明，ＣＭ－９Ｃｂ焊条和新研制的Ｔ９１焊条优于Ｒ３１７焊条，而新研制的Ｔ９１焊条可以代替进口的ＣＭ －９Ｃｂ焊条。

| Abstract: | The diffusible hydrogen content in the deposited metal using CM - 9Cb, R317 and newly - developed T91 electrode was determined through glycerine hydrogen test. and the tendency for hydrogen - induced cracking of the T91/ 12Cr1MoV joint welded with different covered electrodes was investigated by means of electrolytic hydrogen charging and constant - load delayed cracking test. The results from the tests show that CM - 9Cb and newly - developed T91 electrode superior to R317 electrode , and the CM -9Cb electrode can be replaced by the newly - developed T91 electrode. |
