CO2 welding is a welding process that uses carbon dioxide to protect the weld pool from oxidisation during the welding process.
It is also known as Metal Inert Gas(MIG), Manual Arc Gas Shielded(MAGS), welding.
CO2 is not the only gas used, it needs to be heavier than air to work.
The weld pool is, a pool of weld or liquid/molten metal that solidifies as one when finished welding, it is usually between two items so as to fuse the pieces together.
CO2 welding uses a long coil of filler wire that is fed in through the handheld torch, this filler wire melts as it completes the electrical circuit by means of an electric arc which reaches temperature of around 3100 degrees Celsius, and unsurprisingly this melts the metal.
Your question is incomplete. Which process? Which electrode? What is the basemetal, which position? etc etc
CO2 and O2 can not be used in the same time for shielding gas in MIG welding, it would create too much oxidation of the molten metal.
For steel, flux core or hard wire with Argon/CO2 is used with the GMAW process.
The thickness of the laser welding machine depends on the power of the laser generator inside the Laser Welding Machine, the thickness of the object to be welded. These two points are the most important.
Check the shielding gas & its flow rate.

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.
When MIG welding STEEL a mixture of Argon -- CO2 is used. 75% - 25%

For steel, flux core or hard wire with Argon/CO2 is used with the GMAW process.
For example argon or helium for TIG welding. Oxi-fuel welding: oxygen and a combustible gas: acetylene, propane, butane, propylene, gasoline, hydrogen, etc.
On steel a mixture of Argon and CO2 usually 75% to 25%

mig welding is Metal Inert Gas welding. it typically uses Constant voltage DC+ current. It uses a wire feeder that supplies the electrode to the weld puddle and shields the molten weld puddle with inert gas (argon/co2 blend). Filler wire and shielding gas depend on the metal being welded.
== == 95% Argon 5% CO2 is most commonly used for spray MIG.
