Vlastnosti svarových spojů oceli P92 v závislosti na režimu tepelného zpracování po svaření

Abstract

This master thesis is focused on properties control of P92 welded joint depending on post weld heat treatment. Theoretical part of thesis is related to microstructure of modified P92 steel with 9 to 12 percent of chrome. Then is described weldability of homogenous and heterogeneous weld joints of P92 steel. In experimental part of thesis is draft of heat treatment, which was used for welding 8 mm thick plates with 141 welding method. Test welded joints has been submitted to destructive and non-destructible testing. At the end is discussion about achieved results and their comparison with available literary sources.
