what is carbon dioxide used for in welding

Anonymous: Carbon Dioxide (CO2) is the most common of the reactive gases used in MIG welding and the only one that can be used in its pure form without the addition of an inert gas.

Anonymous: CO2 is also the least expensive of the common shielding gases, making an attractive choice when material costs are the main priority.

Anonymous: Pure CO2 provides very deep weld penetration, which is useful for welding thick material; however, it also produces a less stable arc and more spatter than when it is mixed with other gases.

Anonymous: It is also limited to only the short circuit process.

Anonymous: For many companies, including those that place an emphasis on weld quality, appearance and reducing post-weld clean up, a mixture of between 75 – 95 percent Argon and 5 – 25 percent CO2 will provide a more desirable combination of arc stability, puddle control and reduced spatter than pure CO2.

Anonymous: This mixture also allows the use of a spray transfer process, which can produce higher productivity rates and more visually appealing welds.

it is not used in welding.oxygen is used in welding:

explanation:
oxygen combine with hydrogen which form oxy-acetylene flame which is used in welding.
