MAG welding uses active gases such as pure CO2 or mixed gases (argon, CO2, O2) in various compositions. These are highly reactive. The MAG process is used for unalloyed, low-alloy and high-alloy materials. MIG welding, on the other hand, uses inert, i.e

MIG Welding Shielding Gas Basics | Bernard
CO2 is also the least expensive of the common shielding gases, making an attractive choice when material costs are the main priority. 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.

This study aims to reduce the diffusible hydrogen content in deposited metal during gas metal arc welding (GMAW) and flux-cored arc welding (FCAW) which induces cold cracking. To achieve this, a novel welding torch with a dual gas nozzle has been developed. This special welding torch decreases the hydrogen source gas evaporated from a welding wire by the suction from the inner gas nozzle. In

Calculating Weld Volume and Weight - TWI
Fig.1 illustrates how simple this calculation is for an equal leg length fillet weld; the area of such a weld is half the square of the leg length, Z. When using this formula do not forget that welders seldom deposit precisely the size of weld called up on the drawing or in the welding procedure and that there may be some excess weld metal on the face of the weld.
