Metal active gas welding
MAG welding is a metal shielding gas welding process (GMAW) with active gas, in which the arc burns between a continuously fed melting wire electrode and the material. The melting wire electrode supplies the additive filler metal for forming the weld. MAG welding can be used simply and economically with nearly all materials that are suitable for welding. Different shielding gases are used, depending on the requirement and the material.
Versatile and economic
In MAG welding the fed active gas protects the wire electrode, the arc and the weld pool from the atmosphere. This ensures good welding results with high melting rates under very different conditions. Depending on the material, a gas mixture of argon CO2, argon O2 or pure CO2 is used. Different wire electrodes are used, depending on the requirement. MAG welding is a robust, economic and versatile welding process and is suitable for manual, mechanized and automated processes.
MAG welding is suitable for welding unalloyed or low-alloy steels. High-alloy steels and nickel based alloys can also be welded in principle with the MAG process. However, the proportion of O2 or CO2 in the shielding gas is low. Different types of arcs and welding processes are used, such as the standard or pulse process, depending on the requirement for the weld and the optimal welding results.
