Mig welding advantages and disadvantages

Mig welding is a popular method of welding. It is also known as GMAW ie Gas metal arc welding. It is a versatile method of joining complexed metals very easily. But Mig welding advantages and disadvantages depend on the nature of the job you are going to do. So it is quite natural to have a plan for what it will be used to accomplish.

Generally, MIG welders come with single to 3 phases. A single-phase MIG welder 110 or 230 volt generally used in small shops, home garages, art shops and body shops.

These MIG welders present a little bit extra versatility for welding. The 1-3 phase MIG welder can also do the same thing as the single-phase welder do.

You can easily classify the good and bad things of mig welding after you clearly deciding the type of work you do with the mig welder.

MIG Welding Advantages

Easy to learn:

Mig welding is the easiest welding technique to learn. Any newbie can learn it within a week. It only needs adequate training and a little endurance to deliver a great weld in MIG Welding. Some people learn it only following the guidelines provided by the professionals.

Versatile welding:

Lots of professional welder love mig welding just because it can weld a variety of metals like steel, aluminium, mild thicker metals etc without any hassle. Honestly saying that it takes a little time to complete a welding task and cost-efficient also.

High Productivity:

Mig welding method gives high productivity to professionals because there is no changing of rods or brushing the rod repeatedly like other welding. This means it requires less repair and maintenance to supervise. Mig welders can also do his job in different position to deliver the accurate welding by a mig welder.

Clean welding:

Mig welding requires less cleaning since it uses shielded gas to protect the arc. There is a very small chance to waste the alloying parts because the metal transfers throughout the arc. Generally, Mig welding produces less smoke and there are not any slags wanted to be chipped off.

Flexible welding Settings:

Another good advantage of MIG welding is the flexibility of welder settings to operate your welding for specific things. Suppose if you want to weld more plane materials, you can slow down the wire speed which will produce more arc.

Slower wire-speed produces plane weld with deeper penetration and less spatter. Contrarily, if you want to weld thin materials, you can turn down the amperage to minimize the heat. Lower amperage setting helps to weld thinner materials.


If you take a look at small shops or car shops, most of them are using Mig welder because they are faster than other welding methods.

MIG Welding Disadvantages

Inappropriate for outdoor:

As you know that MIG welder uses shielded gas, it is not suitable for outdoor welding because the shielding gas needs to protect the purity to weld. For this, it is difficult to carry and not being portable. In the case of windy weather, it would be hard to lay a good bead.

Mig welder also needs wire roll. Now there’s a method to mix your wire and shielding gas and that’s to make use of a flux-core wire. It is a wire that comprises a middle core of flux when burned will present a layer of safety very similar to a shielding gas.

Another thing is, a quality Mig welder like hobart or lincoln generally weight 65-70 pounds which is much heavier and difficult to move.


Mig welding equipment price is higher and more complexed compared to other welding devices. If any issue comes for repairing or replacement, then it will cost more than you expect.

So before you purchase a MIG welding machine, make sure that you have a pre-idea about which one is perfect for you, its guarantee, and the longevity. Read this article before you make any purchase.

Limitations in position

The high mobility of welding puddle and the high heat input indicates for vertical and overhead welding. Whereas some welders would by no means even consider welding in these positions.

Limitations in welding

Mig welding doesn’t work nicely with rust, soiled surfaces, and paint. Another important thing to remember is, it cannot penetrate well in thick materials. Mig welding also needs much attention while welding.

Quick coling rate

The welded metal will likely be cooled at rates which can be increased since they don’t seem to be coated by slag when the weld is accomplished.

Open arc process

Mig welding must be taken proper maintenance to protect the welder as it is an open arc method like other welding methods.


Lastly, you’ll understand all the advantages and disadvantages of MIG welder. The professionals are certainly further vital than a number of detrimental features of MIG welding device. Apart from, it clearly relies on consumer necessities and preferences of wielding. Hope this information helps you be taught the MIG welding advantages and disadvantages.
