Yes, oxygen is used in a process called oxygen- acetylene welding and brazing. Oxygen- acetylene welding mixes the two gases to producea flame to melt the metal to be welded. Afiller materialisfed into the "puddle" to form the weld. It is used normally on thin metals and cast metals.
Brazing is much the same but the filler material is coated in a flux to keep impurities out of the weld. It is used on cast steels and cast iron.

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 argon is used in welding the recycling companys workbenches?
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.
What is purpose of the flux in welding?
Flux is used to protect the weld from the atmosphere. Flux produces a gas shield over the liquid portion of the weld during the welding process as the electrode is used. The flux then forms a protective layer over the weld called slag. Flux also acts as a deoxidizer, pulling oxygen and nitrogen from the weld pool to the surface, preventing porosity. There are many other and much more technical reasons that involve chemistry of the weld metal, arc characteristics, and mechanical properties of the finished weld.
What is oxygen a solid liqid or gas?
Oxygen is a gas.
Why need to use argon gas for stainless steel welding process?
At the temperature required for welding, austenitic stainless steel passivate so rapidly in the presence of atmospheric oxygen that a strong weld bond can not be formed.

Where can one find information on gas welders?
One can find information on gas welders on a number of websites. Shopzilla, eBay and YouTube are some examples of websites where one can find information about gas welders.

Why CO2 can not be used as shielding gas in GTAW?
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
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".
Can tig welders be used without gas?
Yes you will not get a "good" weld and it will not be strong The filler electrode used by TIG welder is usually bare and need a shield gas to shield off the atmosphere. Without shield gas, air gets into the molten weld usually produce defects called porosity (air pocket). Your finished weld is defective may not meet the strength. Without a shielding gas you will need more power to establish an arc and the weld puddle will be extremely contaminated (oxidized). The electrode (tungsten) will also be contaminated. You will find the arc wandering all over the place. Use a stick welder instead!
Why do they use argon gas to tig weld?
Argon gas is an inert gas and it shields the weld from any contamination from the out side air. It shields the weld and makes it cleaner and stronger.
What does oxygen have to do with welding?
Oxygen is an atmospheric gas that is unwanted in almost all welding processes because in it's molten state, metal oxidizes very easily and causes a weak joint. Weld surfaces are protected during the welding process to keep oxygen from contaminating the weld either by a shielding gas, flux, or in torch welding, the torches own exhaust. Occasionally however, oxygen may be added to the shielding gas mix in small amounts to stabilize the arc and reduce undercutting.
How do you make oxygen gas from chemicals?
you can't oxygen is an element, it cant be made by mixing anything other then oxygen
What is flux coating?
When you weld steel you need to make sure that oxygen in the air is kept away from the weld while it's being formed. Otherwise the iron in the weld burns in the oxygen and forms a poor weld. Electric welding rods are generally coated with a flux which forms a gaseous shield around the weld point and keeps away the air. Some welding processes (MIG for example - MIG stands for metal inert gas) do not use a flux coating but have an arrangement where argon or CO2 is passed to the weld point to keep the air away in a different way.
How do you use for the word Inert?
Argon is an inert gas used by welders.
