Welding gases: which ones should you use?
Welding is a specialised process and requires a specific gas mixture for each process and material.
Gases we use
Since the 70s, welding gases have started an evolution that has accompanied the growth of welding machines, influencing and increasing the processes.

C2H2 Acetylene for welding +
Acetylene for Metalfabrication IndustryAcetylene 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.
-
Ar Argon for Metalfabrication Industry +
Argon for Metalfabrication IndustryThe inert gas par excellence in welding processes. Thanks to the experience of Nippon Sanso as Gas Professionals, we offer you the correct combination of more gases for each application.
-
N2 Nitrogen for Metalfabrication Industry +
Nitrogen for Metalfabrication IndustryNitrogen 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.
-
He Helium for Metalfabrication Industry +
Helium for Metalfabrication IndustryA rare but special gas.
-
H2 Hydrogen for Metalfabrication Industry +
Hydrogen for Metalfabrication IndustryCombustible 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.
-
CO2 Carbon Dioxide for Metalfabrication Industry +
Carbon Dioxide for Metalfabrication IndustryThe active gas most used in welding processes.
-
O2 Oxygen for Metalfabrication Industry +
Oxygen for Metalfabrication IndustryOxygen for Metalfabrication Industry
