在焊接过程中产生的动态应力应变及随后形成的残余应力，是导致焊接裂纹和接头性能下降的重要因素。
The dynamic stress-strain and welding residual stress during welding are the significant factors which lead to welded cracking and debasement of the joint properties.
在焊接试件中有显著的裂纹闭合现象，其原因是焊接残余应力的作用。
There is significant closure in welded specimen due to the effect of welding residual stress.
在排除焊接残余应力导致的裂纹闭合效应后，焊缝及热影响区疲劳裂纹扩展速率与基材相当。
Moreover, the fatigue crack growth rates of the weld metal and heat affected zone are lower than those of the base metal. Having excluded the effect of welding residual tress...
