Gases que utilizamos
Desde los años 70, los gases de soldadura han iniciado una evolución que ha ido de la mano de la evolución de las máquinas de soldar en la utilización y el aumento de los procesos.
Nitrogen for Metalfabrication Industry
Nitrogen 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.
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.
Argon for Metalfabrication Industry
The inert gas par excellence in welding processes. Thanks to the experience of Nippon Gases as Gas Professionals, we offer you the correct combination of more gases for each application.
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.
