Welding is an essential process that involves fusing metals together with potent heat. There are several different techniques, but the most common is metal inert gas, or MIG. Using this method, welders can join metal components together with an arc. Here’s everything you need to know about this popular practice.

What Exactly Is MIG Welding?

The premise of MIG welding is straightforward. It involves using heat to melt materials that form a single joint when cooled. Using metal inert gas is advantageous when you’re working with larger materials. The key element used in this process is a wire rod that behaves as an electrode. Using a welding torch, this wire is fed into a weld pool. The two materials are then melted to create a single component. As the wire rod passes through, a shielding gas made with argon and carbon dioxide accompanies it. This gas protects the integrity of the weld pool from any contaminants present in the atmosphere.  

What Is Its Purpose?

Because this is such a quick process, manufacturers rely on it to produce items at a high rate of speed. Shorter production times lead to reduced costs overall, contributing to a stronger bottom line. It’s typically used for welding sheet metal, producing steel components and structures, and creating pressure vessels to safely contain liquids or gases. Because of the way this process enhances productivity, it’s used across a broad spectrum of industries. For example, automotive and home improvement companies both rely on this weld form to build and assemble major parts. 

What Are Some Safety Tips? 

Always maintain an organized work space to prevent exposure to pollutants as you work. Ensure that there are no unauthorized individuals present while you’re operating your weld torch. For added safety, remove any flammable materials from the area, and ensure proper ventilation. Protect your body with the appropriate personal protection equipment, including a highly rated welding helmet, steel-capped footwear, safety goggles, long-sleeve shirts, pants, thick work gloves, and knee pads if you need to kneel as you work.
