Acetylene for the metal fabrication industry

The synthetic fuel gas.

Fast brazing and cutting

Acetylene is a combustible gas that is obtained only by synthesis. As it is extremely unstable under normal conditions, it is transported in special containers. In these containers, the gas is stabilized by a solvent (acetone or dimethylforlmamide) making it safe to handle the containers. 

Thanks to the high flame temperature it develops, acetylene is frequently used in braze welding processes. In addition, it remains the combustible gas that allows the greatest productivity in this process.

Argon for the metal fabrication industry
Argon is one of the most important gases for the metal fabrication industry. It is colorless, odorless, non-flammable and non-toxic, which ensures that the gas can be used on a very large scale. Argon is generally considered to be one of the best shielding agents, being present in the air. In addition, it is a very favorable gas to maintain the stability of the arc.

Carbon Dioxide for the metal fabrication industry
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.

Helium for the metal fabrication industry
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 for the metal fabrication industry
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.
