Duplex welding of steel using the MAG (Metal Active Gas) method uses a mixture of argon and CO2 to protect the weld bath, allowing for strong and durable joints. Ideal for the chemical, petrochemical and marine industries, it is fast and accurate, suitable for strong materials. Requires correct parameter settings and careful surface preparation. Its durability and strength make it widely used in critical applications such as pressure vessels, pipelines and offshore structures.
