摘要
通过对厚板焊接压杆疲劳对比试验结果进行分析 ,发现厚板焊接压杆在经过一段低应力疲劳之后 ,焊接残余应力峰值明显降低 ,并且残余应力沿板厚方向分布趋于均匀化。
The results about the fatigue comparison test of welded heavy plate is analyzed and it is found that the maximum residual stress is cle arly reduced and the distribution of residual stress on sectioned surface tends to being even along thickness after low-stress fatigue.
