What mode of metal transfer is used with FCAW?

Metal transfer in FCAW occurs in a globular form. The flux inside the core releases gas and slag during welding, which disrupts a smooth, steady spray and causes larger Molten droplets to transfer irregularly across the arc. This results in the characteristic globular transfer pattern, often with noticeable spatter and slag coverage. Spray transfer and pulsed spray require stable, high-energy conditions and shielding gas that promote small, evenly spaced droplets, which aren’t the typical behavior with FCAW’s flux-cored wire. Short-circuit transfer is more associated with low-current solid-wire GMAW (and can occur in some FCAW variants but isn’t the defining mode). So globular transfer best describes FCAW.
