摘要

采用焊接热模拟技术

确定了从焊接粗晶区韧性的角度考虑

取消HCM2S钢焊接对于预热是可行的

其合适的焊后热处理范围为(710～750)℃×2h。HCM2S钢焊接粗晶区在550℃左右时

存在再热脆化倾向

再热脆化的敏感温度范围需进一步研究确定。

Abstract

By using weld thermal simulation technology

and considering from view point of stiffness for the weld coarse crystal region

it is determined the elimination of preheating for HCM2S steel welding is fully feasible

the suitable heat treatment specification to be(710-750)℃×2 h.At temperature about 550 ℃

the weld coarse ccrystal region of HCM2S steel exist tendency of reheat embrittlement

however

the sensitive temperature range of reheat embrittlement is waiting to be further studied and determined.
