Abstract 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.
