Abstract: |
This paper analyzes the welding assembly characteristics of thin shell of aluminum alloy trunk for spaceflight grab. By reducing the welding stress and controlling welding distortion, the optimal weld method and technics propramming are selected. The welding distortion is decreased through a series of tools and more process control. Finally, it satisfies the precision request of product and provides a base for spaceflight garb design and manufacture. |
