提高焊接接头疲劳强度途径的探讨

Improving the Fatigue Strength of Welding Joint

焊接接头的疲劳强度是焊接结构能否承受动载荷的关键指标,它关系到焊接技术在工程中的应用.采用改善焊缝几何形状、减少消除应力、低相变点焊条、覆盖涂层等是提高焊接接头疲劳强度的有效方法.

The fatigue strength of welding joints is the key target if welding structure can bear the living loads, It concerns the use of welding technique in engineering. It is the available ways of improving the fatigue strength of welding joint to adopt amending welding line geometry shape,reducing removement stress, ITFE, covering coat, ect.
