摘 要: 研究了焊接线能量对TA2焊接接头组织和性能的影响。采用不同的焊接线能量焊接22 mm厚TA2焊接接头,对焊接接头显微硬度、拉伸性能、冲击性能、金相组织以及熔敷金属化学成分等进行分析,得出了焊接线能量对焊接接头组织和性能的影响规律。研究表明:对于22 mm厚的TA2合金,如果焊接过程控制合理,焊接线能量对焊接接头组织和性能的影响很小。

Abstract:The influence of heat input on the structure and performance of weld joint was researched. The Vickers hardness, tensile properties, impact properties, metallurgical structure, and chemical composition of the TA2 welded joint with different weld heat inputs were analysed. The relationship between the properties of the welded joint and the weld heat input during the welding was built. The results show that the weld heat input has little influence on the structure and properties of welded joint of 22 mm-thick TA2.

 

Key words: TA2 titanium alloy; welded joint; weld heat input; structure; property
