General principles of formation of residual stresses and strains in welded joints as a result of their local explosion treatment are considered in terms of the elasto-plastic theory. Recommendations on optimization of explosion loading parameters are given. It is shown that results of the treatment do not depend upon the presence and value of initial residual stresses in weld metal.
Keywords: explosion treatment, residual welding stresses, stress relaxation, deformation diagram, Hugoniot curve, shock wave
