What Is Tig And Mig Welding?

Welding is a popular technique for joining and bonding together two separate metal or plastic objects. But did you know that there are two distinct types of welding? The two main types of welding are TIG and MIG welding, and in this article we will be exploring the differences between them.

We will also discuss the different applications for which each type of welding is best suited. In addition, some statistics will be included to illustrate the prevalence of welding in modern industry and manufacturing.

Let’s dive in and explore the wonders of TIG and MIG welding!

What is TIG and MIG Welding?

TIG and MIG welding are two of the most commonly used welding processes in the world today.

It is a process that requires extreme precision and efficiency. The two processes use different techniques, equipment, and materials to ensure the weld is made cleanly and safely.

TIG Welding

TIG (tungsten inert gas) welding is primarily used for aluminum and stainless steel fabrication, but it can also be used for other metals.

The process involves using a thin tungsten electrode and shielding it from oxidation and burning with a steady stream of inert gas. The tungsten electrode is then passed over the material at the desired weld location and the inert gas protects the area from reacting to the heat of the arc.

MIG Welding

MIG (metal inert gas) welding, on the other hand, is most commonly used on steel.

It uses an electrode composed of flux-coated wire that is run along the workpiece. As the electrode heats the workpiece, a gas shield is used to protect the area from contamination.

The gas shield and heat of the arc weld the pieces together, creating a strong and precise joint.

Advantages of TIG and MIG Welding

Both TIG and MIG welding offer several advantages over other welding processes. They provide high-quality and precise welds, require minimal clean up, produce minimal spatter, and create strong and durable joints.

Additionally, both processes can be used on thicker materials and can be used on a variety of metals, including aluminum and stainless steel.

Disadvantages of TIG and MIG Welding

Despite their advantages, TIG and MIG welding also have some drawbacks.

TIG welding requires the wearer to wear a mask, as the process emits dangerously strong ultraviolet rays. MIG welding, on the other hand, requires an electric current to perform, which can be dangerous in certain environments. Additionally, both processes require specialist equipment and materials, which can be expensive. Overall, both TIG and MIG welding processes have their own advantages and disadvantages. However, when used correctly, they provide an efficient and reliable form of welding that produces strong and durable welds.


TIG and MIG welding are two of the most commonly used welding methods in the world today. They can be used on a variety of materials, including aluminum and stainless steel, and offer high-quality welds with minimal clean up. Despite their advantages, they require specialist equipment and materials and require certain safety precautions, such as protective eyewear and electric current avoidance.
