Abstract
Results are given on the use of methods developed for investigation of pressures and strains induced in a welded joint metal loaded by sliding detonation of a cord explosive charge to relieve residual welding stresses. It is shown that the use of the methods makes it possible to obtain sufficiently reliable results needed for theoretical description of the mechanism of relief of residual stresses by explosion treatment of welded joints.
Keywords: explosion treatment, welded joints, detonation cord, sliding detonation, piezoresistive transducer, moire fringe method, residual strain
