Oxygen is used as active gas during MIG welding, spray transfer. It increases penetration and travel speeds. It is used only is small amounts though ususally 1%-5%.

The question mentioned "gas" welding, not any form of electric-arc process, and in oxy-acetylene and oxy-hydrogen welding the oxygen is necessary to raise the fuel-burning temperature to above the melting-point of steel.

How is oxygen used used in welding?
Oxygen is used to produce hot flame which is used in welding purpose
Why is argon gas used in welding?
Argon is used in welding to prevent oxygen from entering the weld site. Oxygen is basicly bad for the weld and Argon displaces the oxygen which results in a better weld (less heat stress, less air pockets (imperfections in the weld) etc.)
Why for welding use oxygen and acetylene?
Because of all the gas combinations used with this process Oxygen and Acetylene, in correct proportions, produce the highest flame temperature.
Which gases are used in normal welding process?
Depends on what you think of as normal welding. Gas welding use oxygen-acetylene. MIG/TIG use Argon. MAG, use an argon-something mix. Depending on what materials you are welding, there are some more options tha might be used.
Which element is used in welding with oxygen?
Acetylene.
Which gas is use in gas welding?
oxygen and acetylene gas Argon gas is used in MIG and TIG welding
What is oxygen used for exept breathing?
Gas welding/soldering/brazing
How is argon used in welding?
As an inert gas, it shields the weld from oxygen and corrosion during the melting process. Tig welding means "through inert gas".
How is oxygen used used in welding?
Oxygen is used to produce hot flame which is used in welding purpose
Why flux is not used in tungsten gas arc welding?
The gas acts as the flux would, in shielding the molten steel from the oxygen in the air.
Why is argon gas used in welding?
Argon is used in welding to prevent oxygen from entering the weld site. Oxygen is basicly bad for the weld and Argon displaces the oxygen which results in a better weld (less heat stress, less air pockets (imperfections in the weld) etc.)
Which gas burns the hottest when cutting torch is used?
oxygen supports the combustion of the gas that one uses in the welding/cutting torch. Acetylene combined with Oxygen produces the hottest flame.
Which compressed gases are used for welding?
For example argon or helium for TIG welding. Oxi-fuel welding: oxygen and a combustible gas: acetylene, propane, butane, propylene, gasoline, hydrogen, etc.
What is an example of active gas?
These inert gases are used in gas tungsten arc welding, and also in gas metal arc welding for the welding of non-ferrous metals. Semi-inert shielding gases, or activeshield gases, include carbon dioxide, oxygen, nitrogen, and hydrogen. These active gases are used with GMAW on ferrous metals.
What is a reaction between acetylene and oxygen that is used in welding metal?
Used in welding metals, the reaction of acetylene with oxygen has = -1256.2= -1256.2 .
Gas used in different types of welding would include what?
Gasses used in welding can include oxygen, acetylene, argon, helium, hydrogen, propane, MAPP gas, and others for special purposes. They may be grouped as oxidizers, fuels and shield gasses.
Why for welding use oxygen and acetylene?
Because of all the gas combinations used with this process Oxygen and Acetylene, in correct proportions, produce the highest flame temperature.
