Which mode of metal transfer is used with FCAW?

Metal transfer modes describe how molten metal travels from the electrode to the weld pool. In FCAW, the flux inside the core melts and provides shielding, which tends to produce larger, less uniform droplets that detach in a globular fashion. This globular transfer is well suiting the flux-cored wire’s characteristics, giving reliable deposition and tolerance to the process conditions without requiring the highly atomized droplets of spray transfer or the short-circuit behavior seen with solid-wire MIG. While spray, pulsed spray, and short-circuit transfers are common in other welding setups (especially with solid wires and specific shielding gases), FCAW typically operates with globular transfer.
