In MIG (Metal Inert Gas) welding, a separate flux is not used. Instead, a shielding gas—such as argon, carbon dioxide, or a mixture—is supplied through the welding gun to protect the weld pool from atmospheric contamination. The flux-cored variant of MIG uses a wire with flux inside, but standard MIG welding relies solely on shielding gas.
