• Impact Values and Fatigue Strength of Weld Metals of Mild Steels and High Strength Steels by CO<SUB>2</SUB>-O<SUB>2</SUB> Arc Welding

抄録

In the case of CO₂-O₂ arc welding of rimmed steel, it was previously shown that the impact values were increased by addition of a certain amount of oxygen to the supplied gas. But if the electrode wire contained a large amount of non-metallic inclusions, the amounts of those in weld metals also increased and consequently, the impact values of weld metals decreased considerably.<BR>In this paper, to confirm this effect of oxygen in supplied gas, some experiments were carried out about impact values of weld metal of semi-killed steel, killed steel, 60 kg/mm² high tensile strength steel and 3.5% Ni steel.<BR>As a result of experiments, impact values of weld metals of these steels were increased by addition of oxygen to the supplied gas up to about 25%. But if electrode wire contained a large amount of in-clusions, such tendency was not recognized.<BR>Such effect of oxygen in supplied gas on the fatigue strength of weld metal was also examined using various electrode wires and base metals. But the fatigue strength of weld metal was not considerably changed by addition of oxygen to the supplied gas up to 10-25%.
