摘要
现代飞机起落架高寿命、高可靠的特点促使了各种新材料特别是钛合金、超高强度钢等材料在起落架上的广泛应用,其中以TC6、TC18等钛合金的应用最为典型。这类钛合金具有比强度高、疲劳性能优良和抗腐蚀性能好等特点,但是钛合金是活泼金属,在焊接过程中易氧化;所以,钛合金的焊接大部分都采用真空电子束焊接或在真空充氩箱内采用全气氛惰性气体保护焊接。从材料和人员设备以及制造过程等方面,研究了TC6钛合金零件在大气环境中的焊接工艺应用及质量控制,并经验证表明,通过合适的工装保护及质量控制,可以获得合格的焊缝。
The modern aircraft landing gear has the characteristic of high life and high reliability, which makes each new material, especially the titanium alloy and ultra high strength steels are widely used in landing-gear, TC6 and TC18 titanium alloy are the most representative. This kind of titanium alloy has advantage such as high strength, good fatigue performance and stress corrosion resistant etc. , but the titanium alloy is the active alloy, so the welding of the titanium is usually use EBW or a box with all the argon. This article is mainly about the welding of titanium alloy in the atmosphere.
