摘　　要：对厚度为70mm的12Cr2Mo1R(正火+回火)钢板的双U形对接焊接接头进行了力学性能试验。结果表明,焊接接头的拉伸及冲击性能均优于母材,各个区域内伸长率一致,塑性良好,脆性转变温度为-55.3℃。The mechanical properties of 12Cr2Mo1R（normalizing ＋ tempering）of double U type butt plate welding joint with thickness of 70 mm was experimented.The experiment results show that,the tensile properties and impact properties of welded joints were better than the parent material,each region has a good plasticity and uniform elongation,the brittle transition temperature was―55.3 ℃.
