摘要
为防止102钢与12Cr_1MoV钢小径管焊接再热裂纹的产生,利用焊接热模拟试验,分析不同焊后热处理温度对102钢试样粗晶区的影响。证明不进行焊后热处理是防止再热裂纹的最佳工艺。
To prevent from cracking of 102-and 12Cr1MoV-small size tubes,the effect of different post-weld heat treatment temperatures on coarse grained region's fearture of such material has been analyzed using synthetic heat affected zone test method. Result indicates the best procedure to prevent cracking is not to do any post-weld heat treatment.
