Plasma-MIG Hybrid Welding for Thick Plate

Plasma-MIG hybrid welding, also known as SUPER-MIG/MAG, is a process that combines plasma arc welding (PAW) and gas metal arc welding (MIG/MAG) into a single welding process. This technology combines the high energy density of plasma welding with the high flexibility and efficiency of MIG/MAG, enabling higher welding speeds, deeper penetration, and a narrower heat-affected zone, and is suitable for welding a wide range of metal materials. The following provides relevant information on the plasma-MIG hybrid welding technology.

Technical Principle of SuperMIG Welding

Plasma-MIG/MAG hybrid heat source welding combines the plasma arc and the MIG/MAG arc into a hybrid heat source, with the filler wire continuously melting and filling the weld pool. The plasma arc is established at the leading edge of the weld and forms a keyhole in the base material. The MIG/MAG arc interacts with the plasma arc, generating electromagnetic forces that pull the plasma arc forward toward the front of the weld pool, increasing the stiffness and stability of the plasma arc, thereby improving weld penetration and welding speed.

Application Cost of SuperMIG Welding

This welding technology helps save usage costs (see the actual cost estimation table below for details). During welding, thick plate workpieces require no edge beveling, no grinding, and no rust removal, and single-sided welding with double-sided formation can be achieved.
