Helium for Metalfabrication Industry

A rare but special gas.

A great help in welding processes

Rarely used pure, helium is an inert gas, very light with high ionisation potential which allows to work with extreme welding parameters.

Normally used in mixture with Argon and other active gases, it increases the heat input on the process allowing to increase the productivity and the protection of the welding bath.

Suitable for all electric arc welding processes (TIG / MIG / MAG) but also plasma and laser, in particular on materials such as aluminium and copper that quickly disperse heat.

Argon for Metalfabrication Industry

The inert gas par excellence in welding processes. Thanks to the experience of Nippon Gases as Gas Professionals, we offer you the correct combination of more gases for each application.

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.
