This study investigates the mechanical properties of ВТ22-alloy samples subjected to restorative argon arc cladding using ВТ22св-filler wire in an argon environment with the application of an external alternating magnetic field, followed by local heat treatment (LHT). The research reveals that insufficient protection during cladding led to defects in the fusion zone of the first group of samples, which reduce their resistance to fatigue failure. The second group of samples, which had pores in the clad layer, exhibits significant variability in service life, as pores located near the hole act as stress concentrators and facilitate crack development. In contrast, the absence of pores near the hole and the application of LHT significantly improve the quality of the clad layer and the heat-affected zone, resulting in substantial service life during fatigue testing. The findings provide valuable practical insights and emphasize the importance of adhering to established cladding parameters, final processing of parts, and LHT regimes to enhance the effectiveness and reliability of the restoration process.
