Welded structures of ship hull elements are subject to high cyclic, dynamic and shock loads during the entire service life, in connection with which the issues of reliability of welded structures are of great importance. Welding, as a technological process, has an undeniable number of advantages, but at the same time has a number of disadvantages that often reduce its effectiveness. One of the main disadvantages is the occurrence of residual stresses due to inhomogeneous heating of the welded structural elements, shrinkage and phase changes. In the current situation, there is an urgent question of finding methods for determining the intensity of stresses and technological techniques aimed at reducing the level and redistribution of residual stresses in the welded hull structure of the vessel.
