Carbon Dioxide for Metalfabrication Industry

The most frequently used active gas in welding processes.

The most important gas in MAG welding

Carbon dioxide is known for its low ionization potential. That is also why this gas is used to generate an electric arc. Nowadays the gas is almost always mixed with argon. Its function is to restore some of the carbon lost during the welding process and to release oxygen as an active gas in the process.

It makes the arc very stable and allows a wide penetration into the joint to be welded.

Acetylene for the metal fabrication industry
Acetylene is a fuel gas which, combined with Oxygen, generates a very high flame temperature and an atmosphere that can be used in braze-welding and other oxy-fuel technologies. Its instability is resolved by storing it in special cylinders that contain a porous mass that is first saturated with a solvent (Acetone or DMF). The Acetylene is than dissolved in the solvent to make it stable and safe to use.

Hydrogen for the metal fabrication industry
Hydrogen is a combustible and very light gas that has the characteristic of binding easily with Oxygen. For its deoxidizing function and the contribution of energy it can give to the welding process, Hydrogen is used, in small percentages, in the TIG and MAG welding processes.

Helium for the metal fabrication industry
Like Argon, Helium is an absolutely inert gas that does not react under any circumstances. Thanks to its ionization potential, it transfers more energy, bringing more heat into the welded joint. In addition, the low specific weight of Helium widens the protection cone, which facilitates the cooling of the welded joint.

Nitrogen for the metal fabrication industry
Nitrogen is a gas which, under normal conditions, is considered as inert. When Nitrogen is subjected to extreme conditions, such as a welding process, it can become reactive. Generally, it's used pure or in a mixture as a backing gas.
