摘　　要：对比分析TB2焊接热输入、焊丝成分、焊接冷却速度等因素对接头性能的影响,讨论了β钛合金焊接保护、杂质含量等方面的特殊工艺要求。结果表明,为达到TB2焊接接头强度和塑性的综合匹配,焊接工艺应采用最小的焊接热输入、最大冷却速度,严格控制保护气体纯度,最大程度降低母材、焊丝及保护气氛中杂质元素含量。The effects of TB2 welding heat input,welding wire composition and welding cooling rate on joint properties are compared and analyzed.The special process requirements of welding protection and impurity content of β titanium alloy are discussed.The results show that in order to achieve the comprehensive matching of strength and plasticity of TB2 welding joint,The welding process should adopt the minimum welding heat input and maximum cooling rate,strictly control the purity of shielding gas,and minimize the content of impurity elements in base metal,welding wire and protective atmosphere.
