摘要
通过分析和试验举例说明了焊接残余应力对焊接接头疲劳强度的影响。为了保证焊接结构可靠性,应采取措施改善和提高焊接接头的疲劳强度。
The effect of welding residual stress on the fatique strength of welded joints was analyzed through the testing.In order to guarantee the reliability of weld structure,some measures should be taken to improve the fatigue strength of the welded joints.
