Abstract

V energetiki uporabljamo visokotrdnostna malolegirana konstrukcijska jekla za gradnjo visoko obremenjenih modernih konstrukcij. Najšibkejši člen varjene konstrukcije je zvarni spoj, v katerem se pojavljajo razpoke, ki lahko povzročijo nenadno porušitev. Zaradi navedenega gradimo zvarne spoje tako, da imajo zvari visoko udarno žilavost, ki lahko zadržijo nestabilno širjenje razpok. V raziskavi je predstavljena eksperimentalna določitev in analiza krivulj Charpyjeve udarne žilavosti v korenu zvara energetske komponente za različne dodajne materiale.

Secondary title: Determination of weld metal impact tougness of energy component
Secondary abstract: High strenght low alloyed steels were used in energy engineering for built up of high loaded modern constructions. The weakest link of welded structure is welded joint where cracks were appeared that can lead to a sudden destruction. Thus, the welded joints are made with high impact toughness that can prevent the unstable cracks propagation. The research deals with experimental determination and analysis of Charpy impact toughness curves at the weld metal of energy component for different consumable materials.
