Welding and Cutting Gases

Quality that can stand the heat

Three product groups for numerous applications. Welding technology covers a very wide range of procedures. The DIN EN 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.

Shielding 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 also indispensable in arc welding, where the necessary thermal energy for the process comes from an arc. The same applies to TIG and MIG 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.

Three product groups for numerous applications

Shielding gases for welding have a major influence on product quality and manufacturing efficiency. For easier selection, you should remember the following names: Ferroline, Inoxline and Aluline. These names stand for gas mixtures that are very specialised in their field:

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

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.

  • MAG welding of plain steels
  • MAG welding of high-alloy steels
  • TIG welding of high-alloy steels
  • MIG and TIG welding of aluminium
  • Forming
  • Plasma cutting
  • Laser cutting
  • Gases for oxy-fuel technology

The gas mix classics
Ferroline C18 with 18% CO2 admixture, Ferroline X8 with 8% oxygen and Ferroline C5 X5 as triple gas mix are proven standard mixes. Oxygen is particularly effective in reducing spatters, while CO2 can be an advantage for out-of-position welding. In special cases, pure CO2 is also used, for example with cored wires for out-of-position welding.

Low-activity gases
With Ferroline C8, as with Ferroline X4, the tendency has been turning to low-activity gas. Reduced slag formation and the avoidance of spatters can bring decisive cost advantages. A positive secondary effect: The mechanical/ technological properties of the weld are noticeably improved. This shows the high quality potential of low-activity gases. C12 X2 and C6 X1 offer the best of both worlds. Here we provide considerably reduced spatter formation and greater suitability out of position welding thanks to the lower O2 fraction.

High-performance welding
At very high current levels, there is a switch from spray arc to rotating arc. Basically, all argon mix gases are suitable for the rotating arc. The lowactivity gas Ferroline X4 renders the switch to rotating arc particularly easy.  Helium admixtures, as in TIME gas for example, are used in special cases. These require a higher working voltage.

Shielding gas for arc welding

Currently, the technology of welding under a protective atmosphere exposed dynamic development. New designs of welding machines produce more high-quality result, reducing the metal scattering through improved transfer of metal. All this eventually reduces costs and improves the quality of the connection. Innovations in welding under a protective atmosphere are introduced substantially simultaneously. Based on long-term experience and cooperation with the parent company Messer, advanced global manufacturer of industrial gases and welding equipment, offers its customers a wide range of products that can improve welding processes while increasing quality and reducing costs.

Welding unalloyed and low-alloyed steels

Manufacture of protective atmospheres for MAG welding unalloyed and low-alloyed steels are based on classical multi mixtures of argon and carbon dioxide under the trademarks FERROLINE C ® 8 and FERROLINE C ® 18, which had long been added to mixtures of argon FERROLINE ®. They include a mixture of the two components FERROLINE ® X 4, FERROLINE ® X 8 and FERROLINE ® S and an assortment of mixtures of three components Ar-CO2 - O2 FERROLINE ® C5 X5, FERROLINE ® C2 X12 and FERROLINE ® C15 X5.

Welding of high-alloy steels

INOXLINE ® - shielding gas mixture, which serves to brew high-alloy steel technology MAG. The range consists of a mixture of argon with a low proportion of oxygen, INOXLINE ® X1 and INOXLINE ® X3, a mixture of argon and carbon dioxide - INOXLINE ® C2, and a mixture of three components (argon / helium / carbon dioxide) - INOXLINE ® HE15 C2. Rapidly growing in popularity trends INOXLINE ® X3, which is available both in gaseous form in cylinders or in liquefied form in mini tanks and stationary cylinders.

Welding of non-ferrous metals

WIG and MIG welding methods are based on non-ferrous metals using pure argon purity 4.6 and 4.8, and helium. Protective atmosphere mixtures Aluline He30, Aluline He50 and Aluline He70 consist of argon and helium, and Aluline N ® is the most suitable for welding light aluminum alloys and copper.

Gases for autogenous technology

Acetylene is a traditional fuel gas for autogenous technology. The high energy flame ensures short piercing times and high cutting speeds. Particularly valued in practice are the optimum results when cutting thin sheet steel.

Typical areas of application are wagon construction and shipbuilding.
