Abstract

Primerjali smo lomno žilavost treh različnih zvarnih spojev, katerih meja plastičnosti je presegala mejo plastičnosti osnovnega materiala. Dva zvara smo v korenskem delu zvarili z mehkejšim dodajanim materialom, da smo lahko opustili predgrevanje. Mehki koren vpliva na znižanje lomne žilavosti spoja. Rezultati merjenja lomne žilavosti so na zvaru, kjer je bil koren izdelan dvovarkovno, višji od štirivarkovnega.

Secondary title: Influence of soft root on weld joint fracture behaviour
Secondary abstract: A comparison of fracture toughness results on three different yield-stress overmatched weld joints was performed. Two welds were made with the soft root to avoid preheating. Soft root lowers the fracture toughness of the joint. The results of fracture toughness measurements on welds with two-pass soft root are higher than those on four-pass soft root.
