航空发动机后壳体组件焊缝去除工艺研究

Research on Weld Removal Technology of Aero-Engine Rear Shell Assembly

航空发动机后壳体组件由蜂窝座和钣金件后壳体焊接而成,零件焊缝去除量大、效率低,因此零件加工增加了车焊缝工序。但由于零件变形较大,采用软爪装夹车焊缝效果不佳,仍留有较大余量。针对这一问题,对车焊缝工装进行改进,解决了零件焊缝去除效率低下的问题。

Aero engine rear shell assembly is made of honeycomb and sheet metal parts rear shell welding,the removal of welding seam of parts is large,low efficiency,therefore,the processing of parts increased the welding process.However,due to the large deformation of the parts,the use of soft jaw clamping vehicle weld effect is not good,there is still a large margin.In order to solve this problem,the welding tool was improved to solve the problem of low removal efficiency.
