自动环焊机在航空发动机中的应用

Application of automatic loop welding in aircraft engine

大量的试验和小批量生产过程中发现,常规的焊接方法如手工氩弧焊、火焰钎焊等在焊接管路时常会出现焊偏、凹陷等缺陷。阐述自动环焊机在航空发动机管路环缝焊接的应用,确定了不同规格管路的焊接参数。环焊焊接过程及焊接结果证明,自动环焊与手工氩弧焊、火焰钎焊相比具有更好的焊缝形貌,形状较为规则,参数和焊接过程的可控性高,生产效率高,具有较高的应用价值。

Through a l.t of experiments and small batch production,usual welding method,for example manual argon arc welding and torch brazing,appear the bugs of deviation welding and depress in wehled tube. In this paper,the application of automatic ring wehling machine in the girth wehting of aeroengine pipe is studied. Confirms the parameter of ring welding for kinds of specification tube,the process and the resuhs of ring wehting show that the automatic welding weld morphology is better than manual argon are wehting and torch brazing,which exhibits regular shape.high controllability and the parameters of the wehling process. The automatic ring welding shows high production efficiency and application wdue.
