Carbon Dioxide for Metalfabrication Industry

The active gas most used in welding processes.

First gas in MAG welding

The characteristic of having a low ionisation potential, meant that this gas was chosen as a vehicle for the generation of an electric arc. Today almost always mixed with argon, it has the function of restoring part of the carbon that is lost during the welding process and of releasing oxygen as active gas in the process.

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

Acetylene for Metalfabrication Industry
Acetylene is the synthetic fuel gas which, combined with oxygen, generates a flame at very high temperature and is the most commonly used fuel gas in braze-welding and oxy-fuel technologies. Its particular instability is resolved by storing it in special cylinders that contain a porous mass which is first saturated with a solvent that Can be Acetone or DMF (Dimethyl Formalamide) which serve to dissolve the Acetylene making it so stable and safe both during transport and in phases of use.

Hydrogen for Metalfabrication Industry
Combustible and very light gas, it has the characteristic of binding easily with oxygen to form water; it is an exothermic reaction, but it has the characteristic of deoxidizing everything it encounters if supported by a little energy. In the TIG and MAG welding processes it is used in small percentages precisely for its deoxidizing function but also for the contribution of energy that it can give to the welding process.

Nitrogen for Metalfabrication Industry
Nitrogen is a gas which under normal conditions is considered inert, but if subjected to extreme conditions, such as during the welding process, it can become reactive. Generally used to inert the ustenitic steels for root protection, it is also used in small percentages in argon for the welding of Duplex and Superduplex steels as it allows to maintain the metallurgical characteristics of these particular steels unaltered.
