The paper presents the results of experimental studies of residual stress in homogeneous steel samples obtained by explosion welding with simultaneous exposure to ultrasound. For experimental determination of residual stress in composites, a method based on sequential removal of thin metal layers from the sample surface and measurement of deformations of the sample from the opposite side using strain gages was chosen. It is shown that the introduction of ultrasound in the process of explosion welding leads to both a redistribution of residual stress and a significant decrease in their maximum values measured in the immediate vicinity of the junction zone of steel samples.

超声爆炸焊接复合材料残余应力研究

本文介绍了通过同时暴露于超声波的爆炸焊接获得的均质钢样品中残余应力的实验研究结果。对于复合材料中残余应力的实验测定，选择了一种基于从样品表面连续去除薄金属层并使用应变计从另一侧测量样品变形的方法。结果表明，在爆炸焊接过程中引入超声波会导致残余应力的重新分布和在钢样品接合区附近测得的最大值显着降低。
