Though they both feature a filled core section and may appear similar at first glance, metal-cored welding wire and flux-cored welding wire offer distinct solutions, each with its own unique benefits for different applications. The main differences between the two that will determine whether you choose one over the other include their composition, the use of shielding gas, their deposition rate, weld quality, welding positions available, and welded material thickness. Metal-cored wire features a different composition than flux-cored wire in that metal-cored wire contains metal powder alloying elements in its core while flux-cored wire contains a flux compound.
Another main difference between the two wire types is that metal-cored welding wire has a higher deposition rate than flux-cored wire, while flux-cored wire has a higher deposition rate than solid welding wire. The higher deposition rate means that the weld is much easier and faster to clean up, producing a smoother bead appearance and providing exceptional efficiency and control. However, flux-cored wire provides superior penetration, giving it an edge over metal-cored wire when welding thicker materials.
Welding position is one of the most prominent differences and may ultimately determine which welding wire is best for your application. Metal-cored wire is limited in that it can only be used in flat and horizontal positions (except pulse welding), while flux-cored wire offers the versatility of several positions, including vertical and overhead welding positions.
Overall, metal-cored welding wire boasts no slag and easier cleanup, making it more efficient with greater control, but it is fixed to flat or horizontal positions. This makes the wire popular for semi-automatic welding. Flux-cored welding wire, on the other hand, offers high versatility in position and use in harsh environments.
There are several benefits you can expect from using metal-cored welding wire like NS ARC Tru-Core® MC welding wire. Here are some of the most prominent benefits this type of wire provides:
Welding using metal-cored welding wire like Tru-Core® MC from NS ARC can help to improve the control and quality of welding operations while providing exceptional efficiency compared to other welding wire types, making it a popular choice in many industries.
