| Abstract: | The article analysed the cause of weld crack produced after welding on 2 25Cr-1Mo steel. It has been shown that the over-high concentration of hydrogen is the major factor producing hydrogen-induced delay cracking in 2 25Cr-1Mo steel. According to the characteristic of the product, the article also introduced a series of suitable repair measures. |
