Flux-Cored Welding: The Basics for Mild Steel | …

Self-shielded flux-cored welding is a wire welding process in which a continuous hollow wire electrode is fed through the welding gun into the weld joint. Self-shielded flux-cored welding differs from MIG welding in that it doesn’t require an external shielding gas, such as carbon dioxide or argon, to protect the weld pool from contamination.

MIG Welding: The Basics for Mild Steel | MillerWelds

MIG welding is an arc welding process in which a continuous solid wire electrode is fed through a welding gun and into the weld pool, joining the two base materials together. A shielding gas is also sent through the welding gun and protects the weld pool from contamination. In fact, MIG stands for metal inert gas.
