Vliv tepelného zpracování dílu vyrobeného metodou SLM na vlastnosti jeho svarového spoje

Abstract

Master thesis is focused on the influence of heat treatment of a parts produced by SLM Method of stainless steel 316L. Theoretical part describes additive technology as a subject and particularly new technology which allow printing out of powder steel in general. The next part of theoretical part shows basic knowledge of welding by method 141 (TIG) also shows some information about tempering. Theoretical part inquires furtherly into the information about stainless steel 316L particularly designed for SLM processing. These information are based on the scientistic articles about the same issue. In the practical part of the thesis were done mechanical tests of welded joint and base material of two welded assemblies. Both parts of each welded assembly were heat treated differently. Practical part also focused on the macro and microstructure of the base material and welding joins of each assemblies. Results of these tests have been compared with another master thesis. This master thesis continues and extends the previous one.
