Welding is a process that joins two pieces of metal by heating them together until they melt and form a joint. Welding is often used to fix things that have been broken, but it can also be used to create new pieces of metal.
Welding is an important skill for anyone who wants to work with metal. It can be used to create all sorts of objects, from simple pieces of metalwork to complex vehicles.
Co2 Welding is a type of welding that uses a gas called CO2 to heat the metal together. This is a more efficient way to weld than traditional welding methods, and it is often used in more difficult situations.
Pure Co2 provides very deep penetration into thin material to weld, and that is useful for welding thick material. Therefore, when it is mixed with other gases, the resulting arc is not very stable and there is more spatter than when mixed with other gases. The area which is to be investigated must be limited to only short circuits.
The CO2 gas reacts with the metal to create a heat and a molten metal. The heat melts the metal and forms a joint. The molten metal then flows into the area that was previously hot, and joins the two pieces of metal together.

How does CO2 affect the weld?
If the welding is done with Co2 it produces a well-formed and strong weld with good mechanical properties. The downside is that it doesn’t produce the most stable arc, and it also tends to generate quite a bit of weld spatter. At the same time, Co2 is not capable of producing the spray-transfer mode in the GMAW process.
Can I use straight CO2 for MIG welding?
All the standard MIG consumables are compatible with pure CO2 shielding gas. To some extent, increased oxidation of Co2 can cause a weld porosity increase.
