Gas mixtures designed to increase the productivit yof your processes.
Quality gases to meet the special requirements of the laser cutting and laser welding process.
Gases and specificmixtures for rootprotection in special welding process.
Specific gases for cutting and brazing metals through oxyfuel technology.
Simple solution for changing and connecting gas bottles, with valve and integrated pressure reducer.
The ISO 9606-1 standard, implemented in 2013, established comprehensive requirements for welder certification. This standard introduced and validated the concept of reducing mixtures in welding processes. For TIG and MAG welding of austenitic steels, this development has significant implications, particularly regarding hydrogen in shielding gas mixtures.
Since the 70s, welding gases have started an evolution that has accompanied the growth of welding machines, influencing and increasing the processes.
Ar 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.
CO2 Carbon Dioxide for Metalfabrication Industry +
The active gas most used in welding processes.
O2 Oxygen for Metalfabrication Industry +
The comburent gas par excellence.
He Helium for Metalfabrication Industry +
Helium is a great help in welding processes.
N2 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.
H2 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.
C2H2 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.
