This article describes the results of the study of optimal conditions for welding alloy products - Inconel 718, made with the method of layered laser growing (SLM). The results of the study of the influence of linear energy, rigid fixation of parts during welding and heat treatment on microhardness, welding deformation and the microstructure of the welded joint are presented.
