The American Welding Society (AWS) classifies all flux filled, hollow-cored wire as, “Flux-Cored wire.” Therefore, the process of using flux-cored wire is called, Flux Cored Arc Welding (FCAW). Since two different types of FCAW wire are available, one needing shield gas, the other not, the defining acronym FCAW, can be additionally sub-egorized into FCAW-S and FCAW-G.

Shielded metal arc welding - McGill University School of …
Shielded metal arc welding (SMAW), also known as manual metal arc (MMA) welding or informally as stick welding, is a manual arc welding process that uses a consumable electrode coated in flux to lay the weld. An electric current, in the form of either alternating current or direct current from a welding power supply, is used to form an electric arc between the electrode and the metals to be

A core composition of a metal-cored wire comprising a coination of graphite and potassium compounds has been proven to stabilize the arc in a straight polarity welding configuration. In particular, adding a coination of graphite and potassium manganese
What Are Different Ways Of Welding Metal?
Flux-cored arc (FCAW) welding: A high-speed, portable wire-feed process that doesn’t require a shielding gas and uses flux-cored wire to shield the arc Note: This sheet metal fabriion technique is effective when welding outdoors, in windy conditions, or on dirty materials.
Gas Metal Arc Welding (GMAW / -MIG-)
Gas Metal Arc Welding (GMAW / “MIG”) The gas metal arc welding (GMAW / “MIG”) process utilizes an electric arc established between a consumable wire electrode and the workpiece. GMAW can be implemented as a manual, semi-automatic, or automatic process, and the flexibility offered by the various process variations is advantageous in many appliions.

Gas Metal Arc Welding (GMAW) is commonly known as "MIG" welding. A continuous-feed electrode (i.e. wire) from a spool is used to supply filler metal directly from the torch tip to the weld. As arcing occurs, the electrode instantly melts and a shielding gas, such as argon, carbon dioxide, or helium, is supplied through the torch tip.
