MIG Welding: Mild Steel Basics

welding supply north carolinaMIG welding (Metal Inert Gas, also known as gas metal arc welding or GMAW) is the most commonly used metal welding technique in the world – it’s fast, inexpensive, and even amateur welders can quickly learn to produce quality work.

Simply put, MIG welding is an arc welding process in which a continuous solid wire electrode is fed through a welding gun and into the weld pool, joining the two base materials together (think of it as a more advanced version of a hot glue gun, but for metal).

The MIG process enables a DIY welder to make, maintain and repair welds on material ranging from 24-gauge up to 1/2-inch thick. With a little practice and some good advice, you can become a competent MIG welder, able to do everything from repairing furniture to building an outdoor fireplace.

Here are some MIG welding basics to get you started.
