Based on the modeling of fatigue crack growth, the method for assessing the life of the welded joints, that give a more complete account of the weld material inhomogeneity, presence of residual stresses, high-amplitude and nonregular loading and other factors have been proposed. The structural-adaptive methods for processing of radiographic images of weld with flaws, that allows to reduce the arbitrary noise without altered of diffusion welding of the nose of air collector for AN-70 airplane engines made from titanium alloy have been improvement. The schemes of the deviation of the thermal and impact treatment of welded joints for reduction of residual stresses have been proposed
