Purpose: To conduct study to obtain data on the appearance and propagation of cracks in the layer that’s welded by induction-metallurgical method, cracks’ impact on exploitation safety of a part and its service age. Methods: Using metallographic studies, the analysis of samples of automatic coupler device with layer, welded by inductive-metallurgical way, was carried out. Results: According to the study results, it was confirmed that cracks do not propagate from welded layer into main metal of a part. Practical significance: The conducted study of crack presence and propagation estimation made it possible to prove further safe exploitation of a part without its performance loss or its structure or technical characteristics deterioration.
