Abstract

The aim of the thesis is to manufacture welded joints on tubes produced by 3D printing namely by the SLM (Selective Laser Melting) and subsequently to find out their mechanical properties and microstructure. To qualify the welded joint a WPQR protocol was created where are said all results of the tests and the necessary information for making a welded joint. The destructive tests are made on the samples among which belong the tensile test, the bending test and the welded joint macrostructure. Visual and penetration tests are included in non-destructive test. Finally, it is assessed whether the welded joint could meet all criteria.
