The oxygen absorption behavior of arc melted pure iron has been investigated in a controlled atmosphere of Ar-O2 or Ar to elucidate the oxygen absorption mechanism of steel weld metal during arc welding process. As the arc current increases, the temperature of arc melted pure iron increases. The oxygen content of arc melted pure iron increased with an increasing arc melting time, and then had a constant value. The constant value of oxygen in arc melted pure iron agreed well with the oxygen solubility calculated from each molten iron temperature.
It is considered that the results apply to weld metals during arc welding process. Therefore, above the 0.01 MPa of oxygen partial pressure, it is probably that the pure iron weld metals absorb oxygen corresponding to the oxygen solubility calculated from the average weld pool temperature.
