This page shows details on the project. The primary projects are displayed together with a list of sub-projects.

Project description:Project is focused on basic research of conditions and procedures of creating the weld joints by laser and electron beam on selected types of duplex stainless steels with ferritic-austenitic structure. Concentrated energy sources, due to their flexibility allow immediate applicaton of preheating before the welding process and post-heating after the welding process using a defocused or rasterized beam, what provides a great research potential. The weldability of duplex and superduplex steels, the structural analysis and the tests of mechnical properties as well as corrosion properties will be investigated in particular stages of the project. All processes of technological network participate on final properties of the product. That is why the experimental research program will also cover analysis of weld joints created from materials influenced by different type and level of deformation as well as the sheet forming of weld joints. Special focus will be devoted to finding the correlation between the crucial technological parameters of the process and properties of performed weld joint. The project has the ambition to push the knowledge boundaries of the welding process of selected duplex stainless steels by the concentrated energy sources, such as laser and electron beam
