Welding is a common technique employed for a variety of applications, from small-scale home repairs to building large skyscrapers. Among its many forms, two of the most popular are MIG welding and Flux Core welding, so what is the difference between them?
With more than 14 million welders involved in the welding profession in the world, it is no surprise that understanding the differences between MIG and Flux Core welding is an important step in deciding which option to use for your specific project. The following article will highlight the differences between these two forms of welding and provide insight into when it is best to use each option in order to get the best results. Additionally, we will explore the touted benefits of each one and examine some statistics related to the welding industry.
So buckle up and let’s dive into the world of MIG and Flux Core welding to better understand the differences between the two.
What is the Difference Between MIG and Flux Core Welding?When it comes to welding projects, the method you choose can make all the difference.
Different methods work better for different kinds of projects. Among the most popular welding options are MIG and flux core welding. Keep reading this guide to find out the difference between MIG and flux core welding and learn which method is best for your next welding project.
MIG WeldingMIG welding stands for “metal inert gas. ” This type of welding is one of the fastest and easiest types of welding to learn and is often the first welding process individuals learn when beginning to weld. MIG welding uses a shield of inert gas that keeps contaminants, like oxygen, from negatively impacting the quality of the weld.
Flux Core WeldingFlux core welding is also known as flux-cored arc welding (FCAW). This method, although similar to MIG welding in many ways, uses a tubular wire electrode containing flux that creates a shielding gas when the welding current is applied.
Having the self-shielded flux in the electrode eliminates the need for an external gas cylinder, making flux core welding easier to use in outdoor welding applications.
How Do MIG and Flux Core Welding Differ?
- MIG welding uses a shield of inert gas for its protection, whereas flux core welding does not, as it obtains its shield from the flux contained within the electrode wire.
- The type of metal being welded is a factor in the choice of MIG or flux core welding. In general, MIG works better with mild steel, while flux core welding works better with thicker metal and materials that have more rust or paint on them.
- Another difference between MIG and flux core welding is that MIG welds are typically cleaner, neater, and have a higher quality finish with no spatter. Flux core welding on the other hand is messier and often results in an inferior weld finish.
- When it comes to cost, flux core welding is cheaper than MIG welding because it requires less equipment.
