What is SuperMIG®
The SuperMIG® welding process allows for the introduction of a plasma electrode within the hybrid MIG welding torch. To establish an arc at the leading position of the welding process, a "keyhole" is created within the parent material by the plasma arc, resulting in deeper penetration. MIG operated typically in the "conduction" welding mode, to fill the void created by the plasma arc. SuperMIG provides an improved MIG welding process resulting in higher quality welds.
The SuperMIG® welding torch uniquely integrates typical consumable electrode (weld wire) and plasma electrode, such that the plasma arc is positioned to lead the consumable electrode (MIG- GMAW) as the welding torch proceeds across the work piece. As seen in the picture, from left to right.
The net result is that the SuperMIG® process combines the key advantages of plasma arc for deep penetration with high arc efficiency and metal deposition of a GMAW.
The interaction between the plasma arc flow and the MIG arc promotes wire heating and current transfer at the end of the weld wire, where the molten weld metal droplets form and subsequently detach.
The magnetic forces, occurring as a result of the interaction of the electric currents passing through the two electrodes, shape the process.
