Flux-cored wires (FCAW, MIG, MAG).
The wire is used for semi-automatic welding of steels in an atmosphere of shielding gases, the recommended combination of gases is M21. Compared to solid wire, they have better welding and technological properties. There are several main types:
Rutile flux-cored wire. It is characterized by excellent weld seam appearance and slag removal.
Basic. They are characterized by high mechanical properties of the weld metal.
Hardfacing. The wire is used for surfacing the wear-resistant surface layer of parts operating in abrasive conditions.
