采用Ｒ－Ｎ全释放解剖法测定了逆焊接加热处理形成的压缩残余应力在复合焊接试板板厚方向的三维分布，采用分段钻孔的方法对压应力层深度进行了验证，取得了比较满意的结果。通过本文工作，提出了一种经过修正的测定高应力梯度下三维残余应力的方法
The full-release anatomic method of R-N was used to measure the three-dimensional distribution of the compressive residual stress formed by the reverse welding heat treatment in the thickness direction of the composite welding test plate. The depth of the compressive stress layer was verified by the segmented drilling method. Satisfying result. Through this work, a modified method for the determination of three-dimensional residual stress under high stress gradient
