摘　　要：采用最大功率为15 kW的TLF15000 TURBO CO_2激光器,对10 mm厚C-22哈氏合金进行了平板对接不填丝激光焊,研究了坡口间隙、激光输出功率、焊接速度、预热温度及保护气体流量等因素对哈氏合金不填丝激光焊焊缝成形的影响,并由此选择出合适的焊接工艺对哈氏合金板进行激光焊接。最后对焊缝性能进行了工艺评定,各项性能均达到使用要求。The influencing factors of weld formation in the laser butt welding of 10 mm-thickness Hastelloy C-22 plates with TLF15000 TURBO CO_2 Laser were analyzed.The influencing factors include the groove gap,laser power,welding speed,preheating temperature,shielding gas flux and so on.The proper welding parameters were obtained and adopted for laser welding of Hastelloy C-22.The welding procedure qualification shows that all the properties of welded joint meet the requirement.
