| Abstract: |
| Aiming at the requirements of high verticality, high roundness and high precision after welding for multi-segment cantilever aluminum alloy complex welding structure, the characteristics and technical requirements of the structure are analyzed. Through the study of welding deformation prevention measures, the welding deformation control technology of rigid fixing and post-welding annealing is determined. The process equipment is designed to meet the requirements of parts positioning, integral rigid fixing before welding and convenient machine loading after welding. The technical requirements of the structure are guaranteed, and the practical basis and technical reference are provided for the manufacture of similar structure parts in the future. |
