Results of investigation of the efficiency of relieving residual welding stresses in joints of low-carbon steel up to 50 mm thick are given. The effect of some factors (ambient temperature, hardening modulus and strength of a material treated, and loading factor) is described. It is shown that the limiting thickness of a metal welded, that "senses" one-sided explosion treatment using detonation cords or a low-pulse explosive charge, can amount to about 50 mm
Keywords: submerged-arc welding, welded joints, lowcarbon and low-alloy steels, explosion treatment, residual stresses, relieving residual stresses, external load, elastic deformation, elongation, calculations, investigations
