Ověření vlastností svarových spojů oceli GX4CrNi13-4 technologiemi 111 a 138

Abstract

In the beginning, the Master thesis is focused on the application and characterization of stainless steel GX4CrNi13-4 for castings, and then on the description of the welding methods 111 and 138 with the corresponding additional welding materials, which are possible to use to weld this steel. In the practical part of this thesis is described experimental verification of properties of welded joints made by 111 and 138 welding technologies, then the pWPS for both methods and description of the implementation procedure tests of welding with their final results. The main task of this work is the comparison of the welding methods in terms of quality and the economic results of the tests specified in the WPQR protocol and productivity indicators and indicators of economics, which enable to infer the conclusion of this work.
