Abstract

This study seeks to characterize the present phases through welded joint zones of structural steel and to describe the fracture mechanism, offering a support to the metallic construction industry. In most cases, structural designers associate weldments in this construction type with the brittleness in its structure, with the drop toughness and with a high collapse risk for the ductile-brittle transition.
