With the increase of yield strength, the longitudinal residual stress of HAZ increases.
且随着焊缝强度增加，热影响区纵向残余应力增加。
When yield strength is equal to the base metal, the longitudinal residual stress is equal to the yield strength.
当焊缝屈服强度与母材相同时，焊缝纵向残余应力高达屈服强度。
The experimental on residual stress of welding joints indicates that the longitudinal residual stress distribution can be obtained.
该方法应用于实际焊缝应力的测量取得了良好的效果。
