摘　　要：钛合金具有优良的耐海水腐蚀性能、高比强度、无磁性等特点,在舰艇建造及海洋工程装备中的应用越来越广泛,T型结构已在舰艇机库、导流罩等船舶部件中广泛引用。针对传统氩弧焊、电弧焊、离子焊等方式的焊接T型结构存在焊接效率低、焊接变形大等问题,设计了钛合金T型结构激光电弧复合对称焊接系统,可以实现T型结构激光电弧复合对称焊接。实验结果表明,当激光功率为12000 W(单侧6000 W),焊接电流为165 A、焊接速度为1.08 m/min、保护气流量为25 L/min时,双侧外观成形良好,焊接接头有效连接,未出现气孔、未熔透等缺陷。Titanium alloy has excellent seawater corrosion resistance,high specific strength,non-magnetic and other characteristics,and is more and more widely used in ship construction and marine engineering equipment,and T-structure has been widely used in ship hangars,deflectors and so on.A titanium alloy T-structure laser arc composite symmetrical welding system is designed to address the problems of low welding efficiency and large welding deformation in welding T-structure of traditional welding methods such as argon arc welding,arc welding,and ion welding.This system can achieve T-structure laser arc composite symmetrical welding.The experimental results show that when the laser power is 12000 W(6000 W on one side),the welding current is 165 A,the welding speed is 1.08 m/min,and the protective gas flow rate is 25 L/min,the double-sided appearance is well formed,the welding joint is effectively connected,and there are no defects such as pores and incomplete fusion.
