Quality that can stand the heat

Welding technology covers a very wide range of procedures. The ISO 4063 standard defines well over 100 different welding methods. The range of gases and applications that Messer offers you in this area is correspondingly diverse.

Gases for welding are typically used in oxyfuel processes, which use fuel gas/air mixtures or, preferably, fuel gas/oxygen mixtures.

Shielding gases for welding are indispensable in arc or laser welding processes. The most famous arc welding processes are MAG, MIG and TIG welding, where gas mixtures dominate today’s market. These mixtures feature a range of possible components, including argon and CO2 as well as oxygen, helium, hydrogen and nitrogen.

A great variety of these standardised gas mixtures is now available for the aforementioned applications. Messer sells its range of shielding gases for welding in a clearly structured system. 

Shielding gases for welding are sold under standardisd, group-wide names which are bases on the materials being worked:

Ferroline - Shielding gases for plain and low-alloy steels
Inoxline - Shielding gases for high-alloy steels and Ni-based alloys
Aluline - Shielding gases for aluminium and non-ferrous metals

Other welding and cutting gases:

Forming gas  - protects the back of the weld against oxidation
Lasline - for processing laser materialand generating the laser beam
Nitrocut and Oxycut - laser cutting gases
Fuel gases - for oxy-fuel technology
Addline - for additive manufacturing

As a manufacturer of industrial gases, we not only deal with those processes that involve the use of industrial gases, but also with processes that are in competition with this. Messer’s advisory service on shielding gases for welding will gladly show you which shielding gas is the right one for your application: in a personal consultation and through on-site demonstrations.
