Argon for the metal fabrication industry

Acetylene is a fuel gas which, combined with Oxygen, generates a very high flame temperature and an atmosphere that can be used in braze-welding and other oxy-fuel technologies. Its instability is resolved by storing it in special cylinders that contain a porous mass that is first saturated with a solvent (Acetone or DMF). The Acetylene is than dissolved in the solvent to make it stable and safe to use.

Carbon Dioxide is the active gas par excellence, especially for carbon steel welding. The energy, coming from the electric arc, separates the Carbon Dioxide into Oxygen, the true active gas in the process, and Carbon. The carbon replaces the gas contained in the steel, which is lost in the welding process, leaving the chemical composition of the welded joint unchanged.

Like Argon, Helium is an absolutely inert gas that does not react under any circumstances. Thanks to its ionization potential, it transfers more energy, bringing more heat into the welded joint. In addition, the low specific weight of Helium widens the protection cone, which facilitates the cooling of the welded joint.

Hydrogen is a combustible and very light gas that has the characteristic of binding easily with Oxygen. For its deoxidizing function and the contribution of energy it can give to the welding process, Hydrogen is used, in small percentages, in the TIG and MAG welding processes.
