Industrial gases towards greater efficiency

Mixtures 1: Welding mixture (Ar = 75%, CO2 = 25%)

Mixture 1 is a two-component mixture comprising 75% argon and 25% carbon dioxide. This mixture is used for Flux Cored Arc Welding (FCAW) of steel and stainless steel, producing lower levels of fume and spatter than pure carbon dioxide. This translates into a healthier workplace environment.

Benefits at a Glance:

1. Good penetration for greater weld depth.
2. Good fusion characteristics for improved weld properties.

Mixtures 2: Welding mixture (Ar = 82%, CO2 = 18%)

Mixture 2 is a two-component mixture comprising 82% argon and 18% carbon dioxide. This mixture produces welds with very good penetration and sidewall fusion, especially when dealing with thicker materials. This reduces the number of defects in the weld, cutting down on rejected components. The high CO2 content helps curbs surface contamination from oil, moisture or rust. This reduces pre-weld cleaning and general manufacturing costs.

Ideal for both dip and spray applications, Mixture 2 was specifically developed for MAG welding of carbon and steel alloys across a range of material thicknesses, particularly in the 5 to 12mm range. It can be used manually or with robotic or automatic equipment.

Benefits at a Glance:

1. Good penetration profile for reduced reject rates.
2. Good fusion characteristics for stronger joints.
3. Reduced prep work and reworking through effective action on surface contamination.

Mixtures 3: Welding mixture (Ar = 90%, CO2 = 10%)

Mixture 3 is a two-component mixture comprising 90% argon and 10% carbon dioxide. This is a good general-purpose shielding gas for MAG welding of carbon and steel alloys. The amount of spatter and slag islands produced by Mixture 3 are low, making it ideal for applications where post-weld cleaning must be kept to a minimum. By saving time, it cuts manufacturing costs. Low surface oxidation also makes it suitable for applications that require post-weld painting.

Mixture 3 can be used manually or with robotic or automatic equipment and is best suited to material thicknesses between 1 and 8mm, although it can be used successfully outside this band.

Benefits at a Glance:

1. Reduced post-weld cleaning with minimal slag on weld surface.
2. Low surface oxidation for enhanced paintability and reduced clean-up time.
3. Low spatter, resulting in less post-weld cleaning and improved paintability.
4. Improved workshop environment with lower particulate fume levels.
