Abstract

The features of the fractures at the beam-to-column welded connections with wide flats or steel plates produced by electric furnaces are tried to be related to the material properties. As the material tests, tension tests for the thickness direction of the plates, V-notch Charpy tests for the base metals and HAZ, hardness tests on the welded zones, furthermore measurements of non-metallic inclusions, grain size, contents of N, 0 etc. are executed. The phenomena of the fractures and ductility capacities of the connections corresponds to these factors of the material properties
