Arc welding

Arc welding include shielded arc welding processes such as gas-shielded metal-arc welding (GMAW) using the MIG/MAG processes. It is possible to weld not only thin sheets with a thickness of 0.7 millimeters or greater, but also thick plates with a thickness of up to 100 millimeters.


What is arc welding?

For shielded arc welding, an arc, a steel wire and a shielding gas are required. The arc constitutes the heat source. The welding wire that is fed automatically and the workpiece are melted and can thus be joined.

Certain gases are additionally used to protect the molten metal against oxidation.

  • For metal active gas welding (MAG), active shielding gases are used, such as CO2, or mixed gases containing CO2 or O2.
  • Metal inert gas welding (MIG) is carried out using inert shielding gases, such as argon, helium or mixtures of these gases.
