A combination of 75% argon and 25% carbon dioxide works well for metal inert gas (MIG) welding applications. This mixture helps to promote a short-circuit arc transfer that enables welding in all positions. Other Ar/CO2 blends are also available.
Welding requires the use of various gases to ensure the best outcome and protect the workpiece and equipment. In many cases, combining two or more gases is necessary to achieve the desired combination of weld quality, travel speed and bead penetration.
Shielding is the primary purpose of welding gases. These inert or semi-inert substances protect the molten weld pool from atmospheric contaminants like oxygen and nitrogen. They also play a prominent role in other welding procedures like weld transfer, bead penetration and arc stability.
If you’re looking for gas welding supplies near you, we can connect you with a full-service Meritus Gas Partners distributor. You’ll always get a high-quality product that adds value to your business and reliable support throughout the purchasing process.
Our suppliers carry an assortment of welding gases and equipment for any application.
Argon is one of the most commonly used gases in welding applications. Argon is a nontoxic, nonflammable and stable gas ideal for shielding due to its ability to disperse contaminating atmospheric elements. It also provides excellent oxidation and corrosion protection.
Examples of the argon blends used in welding include:
A combination of 75% argon and 25% carbon dioxide works well for metal inert gas (MIG) welding applications. This mixture helps to promote a short-circuit arc transfer that enables welding in all positions. Other Ar/CO2 blends are also available.
A blend of 55% argon, 35% oxygen and 10% carbon dioxide is one example of a reliable shielding gas when working with carbon steel. Use it for all metal transfer modes in MIG welding applications. This mixture generates strong weld mechanical properties and reliable arc characteristics.
A precisely controlled blend of these gases can join various stainless steel materials. It performs well in all welding positions and metal transfer types. Nitrogen’s introduction to the mixture optimizes performance by enhancing stability, improving weld penetration and minimizing distortion in the welded workpiece. Good corrosion resistance is another benefit.
An argon and helium mixture is an excellent choice for applications requiring higher heat characteristics. A blend of 75% argon and 25% helium can also increase travel speed in gas tungsten arc welding processes.
A mixture of 90% helium, 7.5% argon and 2.5% carbon dioxide is an excellent choice for short-arc stainless steel welding in all positions. The carbon dioxide component minimizes carbon pickup and improves corrosion resistance, particularly in multipass welds. The high helium content increases heat input.
