The characteristic defects of welding wire and steel studs for arc welding-on, influencing the quality of welded joints, were analyzed. The inadmissible defects of the wire are predetermined by increased total content of nitrogen, hydrogen and oxygen in them, high rigidity, low quality winding on the reels, and the defects of studs are caused by incompliance of chemical composition and mechanical properties with the requirements. 6 Ref., 1 Table.
