CORGON 5S2 is a three-component mixture comprising 93% argon, 5% carbon dioxide and 2% oxygen. This three-part shielding gas is designed predominantly for welding thinner materials. The low levels of carbon dioxide and oxygen in the weld reduce the likelihood of through-burns and holes in the weld area.
The addition of oxygen improves the flow of the molten weld metal, resulting in flatter welds with lower levels of reinforcement. This can greatly reduce the need to machine or grind down the reinforcement – which typically raises stress levels. All of which translates into lower production costs.
This mixture was specifically developed for MAG welding of carbon and steel alloys across a range of material thicknesses. CORGON 5S2 can be used manually or with robotic or automatic equipment and is best suited to material thicknesses between 0.7 and 6mm, although it can be used successfully outside this band.
Benefits at a Glance
Excellent arc stability with minimum spatter for shorter clean-up times and less welding wire
Ideal for welding components that are painted or powder-coated after welding
Reduced likelihood of through-burns and holes in the weld area thanks to low levels of carbon dioxide and oxygen
Improved molten weld metal flow for flatter welds and lower levels of reinforcement
Reduced welding distortion thanks to faster welding speeds and low heat input.
