Popis:	The earthquake that struck Northridge, California, on 17 January 1994, caused collapse of a number of reinforced concrete and wood frame structures. Fracture occurred in welded connections in some steel frame buildings, though none collapsed. Self-shielded flux cored electrodes are popular for steel frame building erection because they are largely unaffected by welding in windy conditions. These electrodes are generally “killed” with aluminium, and the aluminium recovered in the weld deposit affects the microstructure and, therefore, the properties. The paper describes the evolution of steel weld metal microstructures from self-shielded flux cored electrodes, as a function of aluminium content.
