Metal Inert Gas (MIG) / Metal Active Gas (MAG) Welding

Metal Inert Gas (MIG) / Metal Active Gas (MAG) welding refers to a group of arc welding processes that use the heat generated by a DC electric arc to fuse the metal in the joint area. A continuous electrode (the wire) is fed by powered feed rolls (wire feeder) into the weld pool.

Linde has developed serious of MAG Welding gas mixtures to help you maximize the advantages of MIG/MAG welding: 

 - MAG welding of stainless steel: CRONIGON® 2, MISON® 2, CRONIGON® S1, CRONIGON® S3, CRONIGON® 2He20, CRONIGON® 2He50 
 - MAG welding of unalloyed steel: CORGON® 8, CORGON® 10, CORGON® 15, CORGON® 18, CORGON® 25, MISON® 18, MISON® 8, CORGON® 5S4, CORGON® 13S4, CORGON® S8

Tungsten Inert Gas (TIG) Welding 

Tungsten Inert Gas (TIG) welding uses the heat generated by an electric arc struck between a non-consumable tungsten electrode and the workpiece to fuse metal in the joint area and produce a molten weld pool. 
TIG produces very high quality welds across a wide range of materials with thicknesses up to about 8 or 10mm. It is particularly well suited to sheet material. The success of this welding process hinges on various factors such as the choice of shielding gas, welding wire, tungsten electrode and the welding technique.

Manual Metal Arc (MMA) Welding 

Manual Metal Arc (MMA) welding is the most flexible and one of the most widely used arc welding processes. MMA welding can be used to join most steels, stainless steels, cast irons and many non-ferrous materials. For many mild and high-strength carbon steels, it is the preferred joining method.

Metal cored wire welding

Flux-Cored Arc Welding (FCAW)

Flux-Cored Arc Welding (FCAW) uses the heat generated by a DC electric arc to fuse the metal in the joint area. FCAW is a highly productive process for a range of plain carbon, alloy, stainless and duplex steels. It can also be used for surfacing and hardfacing.

Laser welding

Welding gases play an important role in laser welding. Apart from protecting the molten metal and heat-affected areas of the workpiece against the ambient atmosphere, the right gas can increase the welding speed and/or improve the mechanical properties of the weld. Selecting the right process gas is crucial in CO2 laser welding. It is, however, less critical in fibre and diode laser welding.
We can help you choose the gases and supply solution that best fit your laser welding needs.
