Whatever you are going to do that involves a weld, you need to know about the two most common types of welding today: TIG welding and MIG welding. And what is the difference between TIG and MIG welding?
Please read the article below to get the necessary information.
Overview of TIG (Tungsten Inert Gas Welding)
What is TIG?
TIG stands for tungsten inert gas welding, which is gas shielded tungsten arc welding. This method uses a tungsten rod as an electrode.
Tig welding is a type of welding that uses a tungsten electrode to produce an arc between the metal being welded and the electrode. The heat from the arc melts the metal, and the filler material is added to the joint. Tig welding can be done with or without filler material, and it can be used on a variety of metals, including aluminum, stainless steel, and copper.
Pros of TIG
- The welded parts are protected from the atmosphere by gas.
- Electrode feed and filler metal are not compulsory.
- Able to complete a range of projects.
- The final products look beautiful.
Cons of TIG
- Welding rods slow down the feeding process.
- Difficult to install and utilize.
- Hardly handle grime.
Overview of MIG (Metal Inert Gas Welding)
What is MIG?
MIG stands for metal inert gas welding, which is gas shielded metal arc welding. This method uses two electrodes (one is a metal rod, and another is a workpiece).
The heat from the arc melts the metal, and the filler material is added to the joint. Mig welding can be done with or without filler material, and it can be used on a variety of metals, including aluminum, stainless steel, and copper.
Pros of MIG
- Feeding very fast.
- Easy to set up and use.
- Easily process dust.
- Low price.
Cons of MIG
- Flood the welded part with a gas which can’t fuse with the metal.
- Continuous feed electrode wire costs a lot of energy.
- Filler metal is must-have.
- Only suitable for a few tasks.
- The final products are not good-looking.
What is the difference between TIG and MIG?
How they work
– MIG welding runs the additional substance from a spool via a torch. This coil leads the electrical flow, which superheats the material. MIG continuously feeds 2 consumable metallic electrodes to work. Thus it can pour welds very fast.
– TIG welding utilizes a non-consumable tungsten electrode to meld the original metals. After the two types of metal have become liquid, the welder will lather thin layers of the filler material on the weld cleft.
One more difference between the two processes is the amount of time to perform a continuous weld.
A MIG welder can carry out his welding until the wire runs out (normally, a MIG welder should use a 15kg coil, but he can use less in smaller projects).
Meanwhile, a TIG welder will dab thin layers of filler materials on the slits and may need to pause between the 2 layers.
In general, MIG welding only takes time to melt the wire at first before continuously welding. Meanwhile, TIG welding wastes time waiting to dab different filler material layers. Therefore, MIG welding is more time-saving than TIG welding.

Both TIG and MIG welding use a shield during their process. Nonetheless, TIG welding applies pure Argon welding gas (Helium as well), while MIG welding often uses a mixture of 1/4 Argon and 3/4 Carbon Dioxide for less expense.
TIG welding is more flexible and adaptive but more difficult than MIG welding. Thus, the result of TIG welding is always better, and the weld looks nicer.
The TIG welder can alter different filler materials fast and simply by replacing different rods, whereas MIG welding requires changing a new wire.
So, MIG welding is more popular than TIG welding because it can complete the weld much faster.
Kinds of project
MIG welding can handle hard metals, while TIG welding is more suitable for soft alloys.
Welders often apply TIG welding to 5-mm thick metal workpieces such as kitchen sinks or toolboxes. To complete heavier works such as pipe welding, they may need to have a sufficient power source.
MIG welding commonly handles metals at a 40-mm thickness such as mild or stainless steel, and aluminum. Nevertheless, it can be used on a variety of thicknesses from thin sheets of metal to heavier objects.
MIG welding requires DC (direct current) with reverse polarity whereas TIG welding can use both AC (alternating current) and DC (direct current).
When to use Tig welding and when to use Mig welding?
There are a few key factors to consider when deciding whether to use Tig welding or Mig welding for a particular project. First, think about the materials you’ll be working with. If you’re welding metals that are difficult to weld, such as aluminum or stainless steel, Tig welding may be your best option. Tig welding can also be used for thinner metals, which can be difficult to weld with Mig welding.
Another factor to consider is the thickness of the metal you’ll be welding. Tig welding is typically used for thinner metals, while Mig welding works better on thicker metals.
Finally, think about the type of weld you need. If you need a strong, clean weld, Tig welding is usually the best option. However, if you’re working on a project that requires a lot of welding, Mig welding may be more efficient.
Both Tig and Mig welding have their advantages and disadvantages, so it’s important to consider all of the factors before deciding which type of welding is right for your project.

The benefits of Tig welding and the benefits of Mig welding?
There are a few key benefits that Tig welding offers over Mig welding. First, Tig welding is generally considered to be a higher quality weld. This is because the process allows for more control over the weld puddle and provides a cleaner, more consistent weld bead. Additionally, Tig welding can be used on thinner materials than Mig welding, making it ideal for delicate or intricate projects. Finally, Tig welding produces less heat than Mig welding, meaning it is less likely to warp or damage sensitive materials.
What is the main difference between arc welding and TIG welding?
The main difference between arc welding and TIG welding is that in arc welding, an electric arc is used to create heat, while in TIG welding, a tungsten electrode is used. The two processes can be used for different metals and have different advantages and disadvantages.
What is the best welding process?
There is no one-size-fits-all answer to this question, as the best welding process will depend on the specific application. However, some of the most popular welding processes include arc welding, gas tungsten arc welding (GTAW), and flux-cored arc welding (FCAW).
What voltage is needed for MiG welding?
The voltage needed for MiG welding can vary depending on the specific application. However, most MiG welders will require a minimum of 220 volts.
What angle is best for welding?
There is no definitive answer to this question, as the best angle for welding will depend on the specific application. However, a general rule of thumb is to weld at a 30-degree angle.
How many Amps does a TIG welder need?
The amount of Amps needed for a TIG welder will vary depending on the specific application. However, most TIG welders will require between 15 and 20 Amps.
Why does my TIG tungsten turn black?
If your TIG tungsten turns black, it is likely due to contamination. Try cleaning the tungsten with a wire brush or grinding wheel to remove any contaminants.
Why does my TIG torch get so hot?
If your TIG torch gets too hot, it is likely due to poor ventilation. Make sure to have proper ventilation when using a TIG torch to avoid this issue.
What is GREY tungsten?
GREY tungsten is a type of tungsten that is used for welding applications. It is known for its durability and resistance to contamination.
Why is my tungsten melting?
If your tungsten is melting, it is likely due to too much heat. Try reducing the amount of heat you are using when welding.
The main difference between Tig and Mig welding is that Tig welding uses a tungsten electrode to create the weld, while Mig welding uses a wire electrode. -Tig welding is more precise and creates a neater weld, making it ideal for smaller projects or when a high level of quality is required. -Mig welding is faster and can be used on thicker materials, making it better suited for larger projects.
Though I could give you more specific information, all of the above is enough to outline remarkable differences between TIG and MIG welding.
In conclusion, there are many differences between tig and mig welding. From the power source to the filler material used, these two types of welding are not interchangeable.
