| Abstract: | There exist large amount of residual stresses when aluminum alloy structures of electronic equipments are welded and installed. Furthermore, stress corrosion cracks on the structures may emerge due to long period of working under serious corrosion environment, which makes the structure strength and impermeability severely drop. The causes for stress corrosion cracks of the aluminum alloy structures were analyzed. Some process control and improvement measures were put forward. |

| Keywords: | aluminum alloy stress corrosion crack mechanism |
