Nitrogen for Metalfabrication Industry

The inert gas that can become active.

A multipurpose gas in the metal fabrication sector

This gas has the characteristic of being inert under normal conditions, but if subject to high temperatures or to an electric arc it can become active and influence the final result of the process. It is widely used in plasma and laser cutting processes for noble materials such as austenitic or high alloy steels, aluminium.

Nitrogen is used in welding for pure root protection or mixed with hydrogen, or with argon for the welding of Duplex and Superduplex steels.

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.
