Carbon Dioxide iswidely used for MIG welding but I never heard of carbon monoxide and it is definitely not used in the industry as shielding gas. The purpose of the shielding gas is not just shielding the weld pool but offer arc stability with an adequate ionization potential. The heat and electrical conducctivity of the gas at the arc temperature are a huge factor as well.
No, that would defeat the purpose. Shielding gases must be inert (e.g. argon, helium).
As an inert gas, argon is used for shielding very hot metals from the air. Very hot metals, such as the filament in a lighbulb, would react with oxygen and burn in a second or two. The argon gas in the lightbulb keeps that from happening.
Na have higher shielding effect than Li *According to my chemistry book
Argon is used as a shielding gas. By flooding the are of the weld with Argon, Oxygen is kept away from the molten metal of the weld.
shielded metal arc welding does not required any shielding gas
CO2 is an oxygen compound or a non-inert gas,the purpose of a shielding gas is to shield the weld and the electrode from oxygen. argon, nitrogen and helium are the most common gases used for GTAW
Argon is the most common gas used in gas metal arc welding.

The variable parameters for gas tungsten arc welding (GTAW) include; current, arc length, electrode type, electrode size, electrode grind angle, shielding gas type, shielding gas flow rate, and travel speed.
Porosity
The gas acts as the flux would, in shielding the molten steel from the oxygen in the air.
you dont .thats what the flux does.solid core wire needs gas
Ozone
The function of gas collecting bottle is to collect gas.
The shielding braid in a coaxial cable has this function
