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.
What else can I help you with?
How is oxygen used used in welding?
Oxygen is used in welding to increase the burn rate of the fuel gas, such as acetylene, in the oxy-fuel welding process. The oxygen reacts with the fuel gas, creating a high-temperature flame that is used to melt and join metal together. Additionally, oxygen is used in oxy-fuel cutting to aid in the combustion process, resulting in a clean cut through metal.
What is the gas for welding?
Oxygen and acetylene for flame welding. Argon for Tig welding CO2 for MIG welding steels Argon for MIG welding aluminum TRI-mix for robotic mig of steels. And helium is added for some overhead welding.
Which element is used in welding with oxygen?
Acetylene is commonly used in welding with oxygen to create a high-temperature flame for cutting and welding metal.
What are common substances used in fuels for welding?
Common substances used in fuels for welding include acetylene, propane, natural gas, and hydrogen. These fuels are used in conjunction with oxygen to create the high temperature flame needed for welding processes.
Which welding process required o2 gas?
Oxy-fuel welding is a welding process that requires O2 gas. It uses oxygen and a fuel gas, such as acetylene, to create a high-temperature flame for the welding process. The oxygen supports combustion and helps create the heat needed to weld the materials together.
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

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.
What is the gas for welding?
Oxygen and acetylene for flame welding. Argon for Tig welding CO2 for MIG welding steels Argon for MIG welding aluminum TRI-mix for robotic mig of steels. And helium is added for some overhead welding.
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.

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.
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.
Did welders use oxygen gas to weld anything?
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.
