MIG vs. TIG Welding: How to choose between MIG and TIG Welding

The main difference between MIG and TIG is the way the arc is used. The term MIG (metal inert gas) refers to welding that uses a feed wire that constantly moves through the gun and generates a spark. The wire melts to complete the weld. For TIG (tungsten inert gas) welding, a long rod is used to fuse two metals together directly.

MIG vs. TIG Welding 2021

Using the correct welding technique ensures that a wire basket can hold together under load. However, using the wrong welding technique can lead to many problems, such as B. Weaker joints, corrosion of the weld joint, or not completing the weld at all.

MIG and TIG welding both use an arc to make the weld. The difference between the two is the way the bow is used. In TIG (inert tungsten gas) welding, two metals are directly fused utilizing long rods.

Two of the most common welding techniques used in plants in the United States are inert gas (MIG) and TIG (tungsten inert gas) welding.

Both arc welding techniques have their similarities, but there are times when one is more useful than the other. So how do you know when to use MIG vs TIG welding?

MIG vs. TIG Welding : What is MIG welding?

MIG or metal inert gas welding is a process in which a metal wire is continuously inserted into the weld seam. The consumable welding material of the wire acts as filler material to bond the two metal objects together.

To prevent the workpiece from slipping while welding and potentially affecting the angle of the joint, a block of wood is cut with a wood milling machine, which is commonly used to brace the joint.

Then the robot welder moves the welding arm precisely and quickly to evenly distribute the heat after the weld is complete.

What does MIG stand for in welding?    

MIG welding is an arc welding method in which a consecutive solid wire electrode is fed through a welding gun and, MIG stands for metal inert gas.

How MIG Weld?

MIG vs. TIG Welding 2021

The gas mixture used in MIG welding must be different from that used in TIG welding. You don’t want a completely inert protective gas like 100% helium. The arc properties of the MIG process, which uses filler, are very different from the processes in the TIG welding process. Using the wrong gas would, therefore, adversely affect the efficiency of the arc weld.

MIG Welding Procedure

The MIG welder must be properly cleaned after the welding process is complete. A side effect of using a filler material is that a weld seam can cause weld spatter no matter how fast the welder is.

Since the spatter can sometimes cause burrs on the weld joint, which can potentially lead to injury, an additional step of grinding or electroplating may be required to remove these “spatter burrs”.

TIG or tungsten inert gas welding is also known as TIG (Gas Tungsten Arc Welding). TIG welding components include a non-consumable tungsten electrode that passes current through the metals to be joined, a computer-controlled controller for timed welding, and a robotic arm assembly to move the weld tip. Unlike MIG welding, TIG welding may or may not use a filler metal for the welding facility.

What does TIG stands for?

TIG welding is an arc welding method, also known as TIG (Gas Tungsten Arc Welding) in which the TIG stands for tungsten inert gas.

TIG Welding Procedure

Like the MIG welding robots, TIG welding machines are programmed to perform the welding. During the TIG welding process, dangerous sparks or fillers can burn workers.

Rather than risking damage and providing better consistency, robots are programmed to weld while the human welder checks.

During the process, an inert gas is used to protect the weld area from contamination. Common inert gases used in TIG welding processes include argon and helium.

Unlike the MIG process, TIG welding does not always require a filler, but rather when welding metals with high melting points to avoid cracking.

Since fillers can cause weld spatter on the workpiece surface, using TIG welding for direct metal-to-metal welding results in a cleaner and more attractive finish without the need for additional steps such as electropolishing.

MIG welding is the best choice for your job for several reasons. First, it’s more diverse. While TIG welding can be used on more types of metals, its effectiveness is limited on thicker work.

MIG welding can be used on aluminium, stainless steel and steel and any thickness from 26 gauge sheet metal to heavy construction panels.

MIG welding has this great advantage over TIG, as the wire feed not only functions as an electrode but also as a filler.

It allows thicker parts to be fused without even having to be heated. And since the stuffing is used instead of the melt, two different materials can be welded together during MIG welding.


Another reason to choose MIG over TIG is speed. A MIG gun is designed to operate continuously over long periods, making it more efficient and productive than its counterparts. For large industrial companies that require high production speeds, MIG is the way to go. (It’s also suitable for automation). In contrast, TIG welding is a much slower process that focuses on details.


As with any production job, time is money. And because the MIG welding process is so much faster, it’s also cheaper. MIG parts are also more readily available and much less expensive than TIG.


After all, MIG welding is easier to learn and can be perfected after just a few weeks of training. It’s even referred to as the “hot glue gun” of welding – pull the trigger to start or stop welding.

MIG welders can hold and operate the gun with just one hand, which makes it a better option for beginners. TIG welding, on the other hand, is a unique technique in which both hands and one foot have to be used – all with different tasks.

FAQs – Frequently Asked Questions

MIG vs. TIG Welding 2021

Is TIG better than Mig?

TIG welds are more suitable for thinner metals and more modest projects because they form solid and reliable welds. MIG is typically more comfortable to manage and is more adapted for beginners. Welders require to have experience with timing and balancing stuff in both hands.

 Is TIG welding harder than MIG?

TIG is much more challenging to learn than the other types of welding. It needs a highly skilled operator, as it needs the concurrent use of both hands and afoot. MIG welding is also significantly heavier than MIG.and requires the facade of the workpiece is clean.

What do you use TIG welder for?

TIG welders can be utilized to weld steel, stainless steel, aluminum, Nickel, Magnesium, Copper, and even gold. It is a suitable welding method for welding wagons, bike frames, lawnmower door handles, and more.

What is a MIG welder used for?

MIG welding is an arc welding method in which a consecutive solid wire electrode is fed through a welding gun this stands for metal inert gas.


The answer depends on the function. As mentioned earlier, MIG welding is usually better suited for heavy-duty welding jobs where larger, thicker metal pieces are joined together because of the use of filler material.

However, TIG welding can work wonders when joining smaller metal parts, such as the wires for a custom steel wire basket. Because the TIG process connects two metal parts directly together, no filler material can fall out – meaning less money is spent on welding accessories.

With welding machines, TIG welding can be somewhat less maintenance-friendly as the welding process does not constantly use up the welding electrode. It all depends on what “better” means for you and your welding project.

Since its introduction in the US aerospace industry in the 1940s, what we know today as MIG and TIG welding has become an integral part of amateur and professional welding worldwide.

MIG welding is generally considered to be easier and easier to learn and master than TIG welding. The continuous supply makes the MIG process faster than TIG. Since MIG’s filler means you don’t have to heat the workpiece to form the weld fully, it’s likely better for thicker materials, including heavier structural members.
