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.

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.
