Abstract

To understand the influence of minor elements and alloying elements on the toughness of a mild steel and a 50kg/mm^2 class steel, low hydrogen type electrodes of basicity 4.2 was selected for fixing Fe-Ti and Fe-B in the flux respectively 0.7 and 1.5%. From this experiments A-type electrode of 1.15%Mn-0.9%Ni-Ti-B rather than B-Type electrodes 1.35%Mn-0.5%Ni-Ti-B showed superior impact characteristics below -40℃ while upper shelf energy is lowered at the room temperature. Also A-Type electrode showed lower deviation of stable impact value and smooth transition curve at various temperature.
