Carbon Dioxide

 

 

Carbon Dioxide

Carbon dioxide (CO2) is a tasteless, colorless, odorless, nonflammable gas. It is commonly mixed with argon (Ar) as a shielding gas during welding of carbon and stainless steel or in some cases it is used in its pure form. This prevents atmospheric contamination of molten weld metal during gas shielded electric arc welding process.
