Hydrogen for Metalfabrication Industry

Combustible and reducing gas.

Gas with multiple uses in the metal fabrication sector

It can be used as pure or mixed fuel gas, it is widely applied in welding processes mixed in small percentages to Argon as protection gas for the TIG / MIG process of austenitic and copper steels or in MAG welding of austenitic steels.

It also finds application in gas mixtures intended for root protection, but it is not compatible in processes with materials such as carbon steel and aluminum.

Also used in plasma welding (always mixed) for the generation of the plasma itself, but also in the plasma cutting process in considerable percentages for cutting austenitic and high-alloy steels for high thicknesses.

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.
