摘要
对 2 2 5Cr - 1Mo - 0 2 5V钢采取 5种焊接性试验方法 ,确定了该钢不产生冷裂纹的工艺所需预热温度 ,同时也论及了该钢的再热裂纹倾向。试验表明 ,2 2 5Cr - 1Mo - 0 2 5V钢具有较优良的焊接性能。
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.
