That said, when using flux-cored wires, you must purchase the right type based on the weld you need and the material you’re working on. However, another important detail you should be aware of is the wire construction.įlux-cored wires function differently than solid wires because of their flux. The section above shows the main differences between the wires that welders use for MIG and flux-core welding. However, these processes use different wires, which sets them apart.įlux-cored welding uses a tubular wire with flux inside, while MIG welding uses a solid wire. Read on! Wireīoth flux-core and MIG welding use a spool of wire which provides the filler metal to the weld. Therefore, flux-cored welding is more portable, provides more mobility, and makes a better choice for outdoor conditions. One of the most important differences is that flux-core welding doesn’t require gas, meaning there’s also no need for a tank. However, there are situations where one will be a better choice than the other!īelow is an illustration showcasing the process of flux-cored arc welding (FCAW).īelow is an illustration showcasing the basic setup for metal inert gas (MIG) welding or gas metal arc welding (GMAW.) Flux-Core Vs. They’re also versatile as they can weld various materials, including: When it comes to wires, both are equally good and allow you to weld in multiple positions. These welding methods are a much better option for beginners compared to stick welding, where you constantly need to feed the electrodes to the welding machine.Īnother similarity between flux-core and MIG is while flux-core uses only flux-cored wires, MIG can use either a solid MIG wire or a flux-cored wire. That makes the whole welding process much faster, as it’s continuous and uninterrupted. MIG Welding – The Similaritiesīoth techniques are easy to learn and handle as they provide continuous wire feed since both wires act as electrodes.Īlso, MIG and flux-core welding provide an automatic feed to the torch. Stronger than MIG, with better penetrationįlux-Core Vs. If you’re short on time, here’s a quick comparison of the flux-core and MIG welding processes: Wrapping It Up Summary of MIG and Flux-Cored Welding
