| Abstract: | Five kinds of welding test methods were adopted for 2.25Cr-1Mo-0.25V steel. Pre-heating temperature to ensure cold crack will not occur for this kind of steel was determined, and tendency for reheat crack of the steel was discussed. The test showed that the weldability of 2.25Cr-1Mo-0.25V steel is good. |
