The results of the test show that there are different degrees of welding residual stress in main welding lines and some are close to yield strength.
结果表明，锚拉板区域各条主要焊缝都不同程度地存在着焊接残余应力，局部地方接近屈服强度。
The effect of transformation temperature of weld metal on the residual stresses and the fatigue strength of welded joints is analyzed based on their test.
通过焊缝金属相变温度和残余应力测试以及焊接接头疲劳强度试验，分析了焊缝金属相变温度对焊接残余应力和焊接接头疲劳强度的影响规律。
The residual strength is usually used to measure the fatigue failure, but so much work is needed to do and the cost is high and only one data is acquired for one test-piece.
剩余强度来度量疲劳损伤破坏准则清楚明了，但实验工作量大、费用高，并且一个试件只能得到一个数据；
