A marked variation in the oxygen levels was observed ; higher values corresponding to welds made with CO2 shielding. Due to this difference, carbon, manganese, and silicon values were lower for this gas. It has been shown (Ref.5)that when using an Ar/CO2 gas mixture instead of pure CO2 for the same wire, the O content in the gas mixture , originated from the decomposition of CO2decreases, and also the O partial pressure in the arc. A smaller amount of Mn and Si will be oxidized under Ar/CO2 than under CO2,leading to a higher recovery of these elements in the weld metal. Mo and Ni contents were insensitive to the O variations.
