自动氩弧焊工艺在国内航空领域已经是一种成熟的技术,但是按照美国的材料和GE先进发动机的焊接工艺标准进行焊接薄壁的燃烧室机匣内套精密件还是首次。特别是采用带机械手的自动氩弧焊工艺,成功完成了零件试制和批准交付,对于在航空发动机制造领域广泛应用机器人自动焊接技术有着重要的现实意义。 Automated TIG welding is already a proven technology in the domestic aerospace industry, but it is also the first time to weld thin walled combustor case sleeves to US-based materials and GE’s advanced engine welding process standards. Especially, the automatic argon arc welding process with robot has successfully completed the trial production and approval of parts. It is of great practical significance to widely apply robot automatic welding technology in the field of aero-engine manufacturing.
