摘要

爆炸焊接技术是一种高能率的加工技术,在工业实践中得到了广泛应用。爆炸焊接过程产生的残余应力对结构的强度、稳定性有重要的影响。所以需要研究得到合理的残余应力范围,并寻求预测、控制和调整残余应力。采用钻孔法对316L/SA516爆炸复合板残余应力进行试验研究,介绍了钻孔法测残余应力的基本原理、试验准备以及试验过程的注意事项。钻孔法测量试件的残余应力主要分析了爆炸态残余应力、正火态残余应力和爆炸态厚度方向的残余应力。测量结果的发展规律大体和实际一致。

Abstract

Explosive welding technology is a high-energy processing technology,which has been widely used in industrial practice. The residual stress produced by explosive welding process has an important influence on the strength and stability of the structure. So it is necessary to study the reasonable range of residual stress and seek to predict,control and adjust the residual stress. In this paper,the hole-drilling method is used to test the residual stress of 316 L/SA516 explosive welding plate. The basic principle of hole-drilling method for measuring the residual stress,the preparation of the test and the matters needing attention in the test process are introduced. The residual stresses measured by hole-drilling method mainlyanalysis explosive residual stresses,normalized residual stresses and residual stresses in the direction of explosive thickness. The development rule of the measurement results is basically consistent with the actual situation.
