SHIELDING GAS BASICS FOR MIG WELDING

If you’re taking up MIG welding, there are a few things you should know, including the types of gases you can use. MIG welding, which stands for metal inert gas welding, works by consuming the electrode wire, which is fed to the arc zone from the spool. Choosing the correct gases and their quantities is essential when welding, so in this blog, we’ll look at some of the basics for MIG welding, including shielding gases and their uses. What Are Shielding Gases? Simply put, shielding gases have a very distinct purpose in MIG welding. They protect the weld area from oxygen, water vapour, nitrogen and hydrogen. Without this protection, the welding is not done correctly and can lead to several problems, including holes in the weld. There are many different shielding gases, but the most commonly used ones are:
