摘要:

为满足实际工程应用需求，使用自主研制直径4.0 mm的焊条焊接厚度为27 mm的690 MPa级HSLA钢对接接头，研究了不预热(-1 ℃)和低温(66 ℃)预热焊接对焊缝金属的显微组织和力学性能的影响及强韧化机制。结果表明，预热温度对对接接头的显微组织和强韧性有显著的影响。与不预热焊接相比，低预热焊接焊缝金属的强度稍有降低，对接接头的强度变化较小，焊缝中心和熔合线的-50 ℃冲击功(KV₂)变化较大，热影响区的变化较小。低预热焊接的对接接头冷速较低，促进了焊缝金属和熔合区中塑性良好的针状铁素体的生成和贝氏体板条结构的退化，并生成了尺寸较大、数量较多的马氏体-奥氏体(M-A)组元。与不预热焊接相比，低预热焊接的焊缝金属冲击功较高，与针状铁素体塑性、M-A组元与针状铁素体界面结合强度的改善相关。熔合线冲击功较低，与异常长大的针状铁素体、大尺寸M-A组元较密集分布相关。M-A组元与针状铁素体界面结合强度的改善主要与焊缝金属的超低碳含量相关。低预热焊接的对接接头强韧性匹配良好，其抗拉强度平均值为827 MPa，焊缝中心、熔合线和热影响区(熔合线外2 mm)的-50 ℃冲击功平均值分别为99、98和260 J。

Abstract：

In order to satisfy the need of practical engineering application, 690 MPa HSLA steel butt joints with 27 mm in thickness were welded by independently developed electrodes with 4.0 mm in diameter. The effects of non-preheating (-1 ^oC) and low preheating temperature (66 ^oC) welding on microstructures and mechanical properties of butt joints were studied and the mechanisms of strength-toughness were revealed. The results showed that preheating temperature had significant effects on microstructures and mechanical properties of butt joints. By comparison of non-preheating welding, the strength of weld metal slightly decreased while that of butt joints changed within a small range, the impact toughness at -50 ^oC (KV₂) of weld center and fusion line changed obviously while that of the heat affected zone (HAZ) changed slightly. Cooling rate of the butt joint was lower in low preheating temperature welding compared with that without preheating, which promoted the formation of acicular ferrite with excellent plasticity and the degeneration of lath bainite in weld metal and fusion zone. Meanwhile, the M-A with larger size and higher quantity were formed. Comparing with the non-preheating welding, the higher impact toughness of weld metal for low-preheating temperature welding was correlated with the improvements of plasticity of acicular ferrite and interface bonding strength of M-A and acicular ferrite. Meanwhile, the lower impact toughness of the fusion line was correlated with the abnormal growth of acicular ferrite and dense distribution of M-A with larger size. Meanwhile, the improvement of M-A and acicular ferrite interface bonding strength was correlated with ultra-low carbon design of weld metal. Butt joint with excellent strength-toughness properties was obtained in the conditions of low-preheating temperature welding. Mean value of tensile strength of butt joint was 827 MPa, the average -50 ^oC impact toughness of weld center, fusion line, and HAZ (2 mm outside of fusion line) were 99, 98,and 260 J, respectively.

Key words： metallic materials 690 MPa grade HSLA steel butt joint preheating mechanisms of strength-toughness properties
