Q: How does MIG differ from MAG welding?

MIG (131) uses inert gas (argon, helium) and is dedicated to non-ferrous metals and alloy steels. MAG (135) uses active gas (CO₂ or mixtures) and is intended for carbon and structural steels. MIG produces cleaner welds on aluminium, while MAG is more efficient on steels. Our process engineers will select the optimal method for your project.

Q: What materials can be welded with MIG 131?

MIG 131 is dedicated mainly to welding alloy steels and non-ferrous metals: aluminium and its alloys, copper, magnesium, zirconium, and other non-ferrous metals. It is the preferred method for joining aluminium components in aerospace, automotive, and machinery construction.

Q: What is MIG 131 welding?

MIG welding (Metal Inert Gas, method 131) is an arc process in which a consumable electrode (wire) melts under inert gas shielding — argon or helium. The gas protects the weld pool from atmospheric contamination. The method is widely used in industry thanks to its high productivity and weld quality.

Q: How can I order MAG welding at MDP Precision?

Q: How does MAG differ from MIG, and when should I choose MAG?

MAG uses active gas (CO₂, mixtures) and is dedicated to carbon and structural steels. MIG uses inert gas (argon) and is intended for non-ferrous metals (aluminium, copper). Choose MAG when welding steel structures and prioritising productivity and cost. Choose MIG for aluminium and non-ferrous metals.
