MAG welding is a common welding technique that is used in a variety of industries. This method is quite versatile and allows you to get high-quality results. It is used a lot in the metal and heavy manufacturing sectors.
MAG welding process can be mechanized with ease, making it suitable for use in places where a high level of productivity is required. It is often applied in vehicle manufacturing plants at the industrial level. It is also popular with hobbyists looking to build their own leisure vehicles.

In MAG welding, you can also use a special gas-filled welding wire without requiring a separate source of gas. When this wire is combined with a compact and portable welding machine, it generates its own shielding gas.

This removes the need for carrying heavy gas cylinders around and makes this welding process a lot more appealing to hobby welders or DIY people who are looking for a machine they can easily move around.

What Materials Can You Work With?
The possibilities of welding with MAG are limitless, regardless of the type of materials that you want to join. You can use it for almost all kinds of ferrous and carbon steels as well as stainless steel of various thicknesses.
If you are looking to work with aluminum, you don’t need a pulse function for the welding machine. In such cases, the current can be set to alternate between the base current and peak current. This allows you to weld even a fragile material like aluminum in a very controlled way, without burning up the top surface.

In the case of welding higher alloy steels and aluminum, you can increase the volume of inert gases like helium or argon in your mix to reduce the intensity of the weld. The advantage of adding inert gases to the mix while MAG welding is that they allow you to meld with higher temperatures without oxidizing the material.

Where Can You Use MAG Welding?
MAG welding can only be used indoors or in enclosed spaces where you have ample protection from the wind. This is because the gases used in MAG welding don’t provide very good coverage like pure Argon or Helium.
Strong wind, moisture, and rainy weather can easily blow away the shielding gas and expose the welding bead to oxidation. This can create porosity and lower the quality of the final weld.


Types of Arcs Used in MAG Welding
Four types of arcs are mainly used in MAG welding to weld metals together.

Short Arc Welding
Short arc welding is used if you are working with really thin metal sheets, delicate projects, and soft metals or if you are welding from a difficult position. A short arc weld produces a fine droplet, creates low sputter, and results in a smooth material deposit.
Long Arc Welding
The long welding arc is used for thick metal sheets and plates. It generates a long arc and uses a spatter-intensive technique that produces a coarse material deposit.

Spray Arc Welding
Spray arc welding is used by expert MAG welders or automated machines. It is used for welding together thicker sheets and plates with the help of an argon-based mixture of gases.

You can achieve a larger melting area on metal sheets and greater welding speed with spray arc welding. It produces a very low spatter and creates a fine droplet of material deposits.




Why CO2 is used in MAG welding?
Carbon Dioxide is one of the most reactive gases. It offers great metal penetration while providing adequate shielding for the arc. It is one of the few gases that can be used in MAG welding in its pure form without the addition of inert gas, making it very cheap as well.

What is the advantage of MIG welding?
MIG welding offers a much better quality finish than MAG welding. It is ideal for use in thin metal frame projects where you need to work on surface plating or delicate material.
