| 摘 要： | 通过对典型焊接构件焊缝的宏观、微观组织分析及力学性能测试，确定该构件的疲劳强度不足主要是焊接中存在的未焊透，起弧处、熄弧处缺陷较多造成的，热影响区并非薄弱点。

| Abstract: | Macroscopic and microscopic structure analysis and mechanical properties testing of welded seam showed that main reasons of low fatigue strength were non-penetration welded seam, many flaws in positions of arc starting and suppressing, but not weakness of heat effeced zone as for typical welded component. |
