摘　　要：钛合金具有高熔点、高化学活性、低导热系数等特点,在军事及民用领域有巨大的应用潜力。但厚壁钛合金构件的焊接工艺仍面临着诸多难点,如焊接效率低、组织性能不均匀、接头塑韧性不足等。本研究针对厚壁钛合金构件的焊接生产,总结了电子束焊、钨极氩弧焊、熔化极惰性气体保护焊、真空激光焊四种焊接工艺的研究现状,梳理了存在的问题和相应的工艺措施,并对厚壁钛合金构件高效高质量焊接工艺的发展趋势进行展望。Due to characteristics such as high melting point,high chemical activity,and low thermal conductivity,titanium alloys have great potential for application in military and civilian fields.However,the welding process of thick-walled titanium alloy components still face many difficulties,such as low welding efficiency,uneven microstructure and properties,and insufficient joint plasticity and toughness.In this paper,the research status of four welding processes for producing thick-walled titanium alloy components is summarized,including electron beam welding,tungsten inert gas arc welding,gas metal arc welding,and vacuum laser beam welding.The existing problems are identified,so are the corresponding process measures.The development trend towards achieving high efficiency and high-quality welds for thick-walled titanium alloys are prospected.
