Product Description
The CO2 Welding Wire ensures a stable arc as well as smooth flow in all ambit of currents. It ensures less spattering under optimal welding conditions. This ensures welding in all postilions and gives supreme protection from moisture and dirt. This wire assists in the welding tasks during the construction as well as handling of ships, construction equipment, vehicles, steel frames, bridges. The CO2 Welding Wire is applicable for frames and brackets, automobile silencers, boilers, automobile body, petrol tanks, cycle spare parts, LPG gas cylinders, railway wagons, steel furniture, compressors, scaffolding & some other welding in all-purpose steel fabrication. This wire boosts a high welding speed as well as enhanced rust protection.
Offered welding wires have copper coating (double de-oxidized) and their thickness ranges between 0.8 mm to 1.2 mm. Per roll, these contain 15 kg amount. These wires are suitable for MIG welding. Due to their high tensile strength, such wires can be used on steel surfaces that have moderate amount of scaling and corrosion. These types of wires show excellent conductivity when exposed to high temperature. Offered wires are suitable for designing structural pressure vessels and boilers. These contain maximum 1% carbon, up to 1.2 % manganese, 0.03% phosphorous, maximum 0.50% silicon, 0.50% copper and 0.04% sulfur. Their elongation is 22 minimum and their tensile strength ranges between 470 Mpa to 500 Mpa. Advanced processing method of such wires prevents these to form slag. Minimal spatter loss and stable arc are some of their main aspects. High penetration rate and deposition rate are undoubtedly some of their key features. These are required during welding of pipes, for construction of bridges, for manufacturing pressure vessels and structural steel, etc. Spool based packaging standard of these products conforms to DIN norms.

# Frequently Asked Questions:
Q. What is CO2 welding wire?
Ans: CO2 welding wire is a type of filler metal used in the process of Metal Inert Gas (MIG) welding, which is also known as Gas Metal Arc Welding (GMAW). It is a solid wire electrode that serves as the consumable material to create the weld joint by melting and fusing with the base metal.
Q. What is the composition of CO2 welding wire?
Ans: CO2 welding wire is typically made of mild steel and contains a specific combination of alloying elements to enhance its welding characteristics and mechanical properties. The precise composition can vary depending on the manufacturer and the type of welding application.
Q. Why is CO2 used as a shielding gas for MIG welding?
Ans: CO2 (carbon dioxide) is commonly used as a shielding gas in MIG welding because it is readily available, cost-effective, and provides good weld penetration. When CO2 is introduced as a shielding gas, it protects the weld pool from atmospheric contamination, preventing oxidation and ensuring a clean and strong weld.
Q. What are the advantages of using CO2 welding wire?
Ans: CO2 welding wire offers several advantages, including:
1. Cost-effectiveness: It is relatively inexpensive compared to other shielding gases, making it a popular choice for various welding applications.
2. High penetration: It provides good weld penetration, making it suitable for thicker materials.
3. Versatility: It can be used for welding a wide range of materials, including mild steel and some low-alloy steels.
4. Availability: It is widely available, ensuring a steady supply for welding operations.
Q. Are there any limitations of CO2 welding wire?
Ans: Yes, there are some limitations to using CO2 welding wire:
1. Increased spatter: CO2 can produce more spatter compared to other shielding gases, leading to more post-weld cleanup.
2. Weld quality on thin materials: While CO2 is excellent for thicker materials, it may not be as suitable for welding thin sheets due to potential burn-through and lack of fine control.
Q. Can CO2 welding wire be used with other shielding gases?
Ans: Yes, CO2 welding wire can often be used with mixed shielding gases, such as a combination of CO2 and argon. This mixture is known as C25 (75% argon and 25% CO2) and offers some benefits over using pure CO2, such as reduced spatter and improved weld appearance on certain materials.
Q. How do I select the right CO2 welding wire for my project?
Ans: The selection of CO2 welding wire depends on the base metal being welded and the specific requirements of your project. Consider factors like the thickness of the material, the welding position, and the desired mechanical properties of the weld joint. It is best to consult with welding suppliers or experts to choose the appropriate wire for your application.
