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.

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.

Carbon Dioxide for Metalfabrication Industry

The active gas most used in welding processes.

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.
