| Abstract: |
| In view of the complex space structure and low degree of automation welding of tube products in launch vehicle, the technology of first welding together then bending for tubes was discussed. The rule of spring-back and extension of tubes was obtained, and then the accurate bending of tubes was realized by predicted in advance and corrected, which provided the basis for subsequent automatic welding of tubes. |
| Key words: tube first welding together then bending spring-back extension |
