When Was MIG Welding Invented? Plus Best MIG Welders of 2022

MIG welding is one of the most popular types of welding. It is a process that uses a continuous wire feed to join two pieces of metal together. MIG welding is often used for welding aluminum and steel, and it can be performed with or without shielding gas.

MIG welding was invented in the 1940s in the United States. MIG welding quickly became a mainstay due to its ease of use and versatility. Today, it is one of the most commonly used types of welding.

There are several welding methods used today but the electrode arc welding method remains the most common and popular. In this family, there are three sub-categories viz. Stick, MIG, and TIG.

In this guide, I will talk about MIG welding with a focus on the following topics:

  • The history of MIG welding
  • Best 220, 110 and Multi MIG welders
  • And some other FAQs on the topic.

History of MIG Welding

MIG welding stands for Metal Inert Gas welding. It was first invented in 1948 and patented for use in the USA in 1949. The invention can be attributed to the Batelle Memorial Institute under the sponsorship of the Air Reduction Company.

Some experts believe that MIG welding came into existence so welders could weld aluminum cleaner and faster than stick welding and TIG welding.

Just like in arc welding, the heat for MIG welding is produced by an electric arc. The main difference between arc (stick) and MIG welding is that in place of a filler rod, a handpiece connected to the electrical source feeds a continuous wire of the same metal you are welding. Thus, it acts as both the electrode and the filler material.

The benefit of MIG welding is that the handpiece emits an inert gas that protects the molten metal from oxidation when it forms the weld. This gives rise to cleaner welds.

When Did MIG Welding Become Common?

MIG welding became especially popular in the 1950s. This was also a time when car manufacturers started using thin-gauge HSLA (high-strength low-alloy steel) sheets.

Carmakers insisted that the only way to weld together HSLA sheets with other thin gauge steel was using MIG welding. It was clear for everyone to see that the process created clean welds.

Here are some other properties and benefits of MIG welding that make it so widespread:

  • Even a hobbyist or a DIY enthusiast can easily create a professional-looking seam with minimum training and practice.
  • The localized heat ensures minimum panel distortion. Also, because of its limited heat buildup, it is ideal for filling unwanted holes in the body panels.
  • MIG welding also duplicates the factory method of joining various body assemblies.
  • Another big reason behind MIGs popularity is its speed. Thanks to the continuously fed wire electrode which does not need changing as frequently as does stick welding, you can get the job done a lot faster. This means that you can just continue welding without having to stop for changing the welding electrode.
  • Last but not least is the minimum cleanup with MIG welding. The low amount of slag and splatter produced not only gives you a better welding experience but also a pleasant cleanup experience.

When Was Gas Metal Arc Welding Invented?

In the United States, MIG and MAG (metal active gas) welding are referred to as GMAW  or Gas Metal Arc Welding.

The basic concept of Gas Metal Arc Welding or GMAW is the same. It involves the production of heat using a workpiece and a metal electrode. The heat produced by the electric arc creates a weld pool that fuses the joint. The entire process takes place in the presence of a shielding gas that prevents contaminants from getting into the weld.

The invention of Gas Metal Arc Welding can be attributed to C L. Coffin, who first demonstrated the process in 1890. However, it was only refined in the 1920s by HM Hobart and PK Devers, who used different shielding gases like helium and argon.

The process of GMAW or MIG welding only became commercially available in 1948.

As I mentioned in my review above, the Weldpro MIG 220 is a versatile and convenient welder.

Do You Have to Use Gas with MIG Welder?

The full form of MIG is Metal Inert Gas. So, technically, you need to use gas with MIG welders. However, many brands promise ‘gasless’ use.

In reality, there is no such thing as gasless MIG. The ones that claim to be gasless use the flux core. The flux core technology creates a shield and converts the flux into gas.

Also, it reduces power consumption while improving arc output.

What Is MIG Welding Used For?

MIG welding is versatile, convenient, and super fast. Its features find its many applications as follows:

¼ inch plates

Since the distortion of thin gauge sheet metal is kept to a minimum due to the lower current used, it is ideal for welding ¼ inch plates. They need less than 20V.

Students and beginners

Since the process is easy and safe to learn, it is ideal for beginners, hobbyists, students, and those who do light fabrication or maintenance work from time to time.

Filling in gaps

Gaps are easy to fill with MIG welding since one can make multiple welds, one on top of the other.

All types of metals with one wire

This is the most elegant aspect of MIG – you can weld multiple metals with one standard wire.

Overhead welding

MIG welding can be used for overhead or vertical jobs with little spattering.
