摘要
焊接结构能否承受交变动载荷主要是看焊接接头的疲劳强度。应力集中是造成焊接疲劳的一个重要因素,采用改善焊缝几何形状、焊接接头类型等措施来降低应力集中可以有效地提高焊接接头的疲劳强度。
Fatigue of welded structures often generates at the welding joints. The load bearing capacity of a welded structure depends on the fatigue strength of the welded joint. The stress concentration is an important factor influencing welding fatigue. Improvingthe geometry of welding seam and the type of welding joint can effectively improve the fatigue strength of welding joint.
