According to the problems existing in the production of aircraft tube

the key technologies of digital assembly tooling and automatic welding on the aircraft welding tube are researched

which can shorten the design cycle of tube tooling

improve the accuracy of tube fixed position and the tube manufacturing precision. The establishment of mathematical model of welding tooling using digital design method

the positioning and clamping of the tube welding are realized by the method of hole location

the automatic welding is completed through coordinate conversion

seam tracking and modification

and digital manufacturing of the welding tube is realized.
