| 中文摘要: |
| 舰船电子装备铝合金结构件在焊接加工、安装中余留了大量应力，并且长期工作于恶劣的腐蚀环境，导致出现应力腐蚀裂纹，使结构件强度或密闭性严重降低。分析了应力腐蚀裂纹发生的原因，提出了工艺控制及改进的措施。 |
| 英文摘要: |
| 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. |
