Abstract:V diplomski nalogi smo analizirali vplive parametrov varjenja na kakovost zvara, pri varjenju temperaturno odpornega jekla X10CrVMoNb9-1 (P91).Izvedli smo mobilne in laboratorijske meritve trdote (po Vickersu) v osnovnem materialu in v varu, izvedeli smo tudi natezni preizkus preko vara. Meritve smo izvedeli na štirih vzorcih, ki so bili iz proizvodnje izločeni, zaradi neustreznih trdot in pomanjkljivega nadzora nad samim varjenjem. Pridobljene rezultate smo primerjali s tistimi zapisanimi v pristojnih standardih. V diplomski nalogi pa smo tudi analizirali vplive temperature in časa na odpornost jekla P91 proti lezenju, ter vpliv toplotne obdelave pred in po varjenju.

Title:The weldability of newer heat-resistant materials and their use in termoenergetic components
Abstract:In the thesis we analyzed the effects of welding parameters on the weld quality of temperature resistant steel X10CrVMoNb9-1 (P91). We performed mobile and laboratory measurements of hardness with Vickers tests on the raw material and on the weld, and we also performed a tensile test on the weld. The measurements were carried out on four samples that were withdrawn from production due to their inadequate hardness and lack of supervision during the welding process. The results obtained were compared with those written in the official standards. The thesis also analyzed the effects of temperature and time on the creep resistance of P91 steel and the influence of pre- and post-weld heat treatment.
Keywords:steel X10CrVMoNb9-1, parameters of welding, hardness test, tensile testing, creep resistece, heat treatment
