The complex physical process of welding residual stress relieving by means of explosive technique is studied experimentally and numerically. The experiments are carried out in welded 16 MnR steel plates. In the numerical simulations, the explicit dynamic finite element method is adopted. The results from experiments and computations are consistent with each other. The mechanism of this technique is explained by considering the effect of stress wave reflection and superposition on the redistribution of stresses in this process. Based on the above studies, some advises and parameters are provided to practical applications of this technique.
