摘要 通过选择钛碱性渣系和Mn-Si-Ni-Ti-B合金系,在德国进口无缝药芯焊丝生产线上,制成了一种超低氢高韧性的无缝药芯焊丝TME711Ni SF.其焊接工艺性能和力学性能优良,对焊接热输入具有良好的适应性.为探讨熔敷金属的韧化机理,对配方中的脱氧剂和合金剂含量进行了优化设计.结果表明,Mn和Si元素含量居于优化水平时,焊缝组织主要是均匀细小的针状铁素体,这种组织的塑性和低温韧性高,熔敷金属在温度-40℃冲击吸收功可达到154 J.该无缝药芯焊丝熔敷金属的扩散氢含量为2.4 m L/100 g,达到了超低氢水平,适用于船舶、桥梁、海洋工程等重要结构的焊接. By choosing Ti-based alkaline slag and Mn-NiSi-Ti-B alloy system,a kind of seamless flux cored wire named TME711 NiS F with super low hydrogen and high toughness was developed on the seamless flux cored wire production line imported from Germany. The seamless flux cored wire has excellent welding technology,mechanical properties and better adaptability to heat input. In order to investigate the toughening mechanism of deposited metal,the contents of deoxidizer and alloying agents in the formulation were optimized. The results show that when the contents of Mn,Si were at the optimized levels,the microstructure was mainly composed of uniform and fine acicular ferrite with good ductility and toughness. The- 40 ℃ impact absorbed energy of deposited metal can reach up to 154 J. The diffusible hydrogen content in deposited metal reached the super low hydrogen level with 2. 4ml /100 g. It can be applied in welding important steel structures of ships,bridges and marine engineering,etc.
