This work deals with the influence of heat treatment and TIG welding technology on the mechanical properties and microstructure of welded joint. The weld was performed on a product from austenitic 316L stainless steel which was made by using SLM additive technology. In the experiment, test welds were welded and subsequently non-destructive and destructive tests were performed, including evaluation of the microstructure. All samples were evaluated as satisfactory by non-destructive tests. The tensile test was performed both for the welded joint and for the base material in the transverse and longitudinal direction. The values of the yield strength of the samples with the welded joint correspond to the values required for the base material - forged steel 1.4404. Microstructural analysis revealed significant differences between samples with and without heat treatment.
