What is the best gas for MIG MAG (GMAW) welding on carbon steel?

The definition of the best gas in MIG MAG welding in carbon steel, can help your company close more proposals, make it more competitive without compromising the quality of welding services or production.

In MIG MAG welding for carbon steels, the gas for welding or mixing gases has the function of protecting against oxidation and atmospheric contamination, but it affects the points below:

ÍNDICE:

1. Productivity GMAW Welding – Carbon Steel

Considering a gas mixture combining Argon and CO2, as the Argon concentration increases in the mix, the melt puddle fluidity also increases and the welder’s productivity can increase up to 4x when compared to a 100% CO2 protection atmosphere.

Productivity GMAW Welding – Carbon Steel

2. Spatters GMAW Welding – Carbon Steel

In addition, a higher concentration of Argon in the mixture with CO2, will bring the benefit of less spatter generation and therefore, less rework in the post weld.

Spatters GMAW Welding – Carbon Steel

3. Fumes GMAW – Carbon Steel

A higher content of Argon in the mixture with Carbon Dioxide also contributes to the work environment and health of the welder, as it reduces the generation of fumes from the MIG/MAG welding process.

4. Penetration GMAW Welding – Carbon Steel

On the other hand, the carbon dioxide content contributes to increase the penetration of MIG MAG welding, so, with the increase of the argon content in the mixture with CO2, the penetration decreases in relation to the welding carried out in an atmosphere with 100% dioxide of carbon.

Penetration GMAW Welding – Carbon Steel

CONCLUSION

Considering the information above, it is possible to understand that the best gas for MIG MAG welding (GMAW welding) is a gas mixture of Argon and Carbon Dioxide. The concentrations of these gases in gas mixture, must be defined taking into account the balance between productivity, amount of spatter, fumes volume and weld penetration required for each welding application, product or welding service or task.
