Welding is more than just heating and fusing wires. There are specific techniques to weld and give metals a particular form. It is crucial to use the right technique, or it may lead to corrosion of weld joints, weaker bonds, or failing to complete the weld at all.
MIG (inert metal gas) and TIG (inert tungsten gas) the two most common welding techniques used. Both of these arc welding techniques have their similarities, but at times one might be more useful than the other.
MIG welding is the continuous feeding of the metal wire into the weld being made. The consumable welding supply of the wire acts as a filler material to join the two metal objects. This process is called GMAW (Gas Metal Arc Welding).
The gas blend used in MIG welding is different from that of TIG welding. You cannot completely inert shielding gas, such as 100% helium. This is due to the arc characteristics of the MIG process—so using the wrong gas would negatively impact the efficiency of the arc weld.
TIG Welding is also known as GTAW (Gas Tungsten Arc Welding). TIG welder parts have a non-consumable tungsten electrode through which the current runs. TIG welding procedure may or may not use a filler metal for the welding supply.
Here are the differences between MIG and TIG Welding:
MIG is more diverse than TIG. As MIG has a filler, it can be used to weld two different metals together.
MIG is designed to run continuously for long periods. It is more efficient and productive, so it is mainly used in industrial operations that require high productions. In contrast, TIG is a slower method but provides a high level of detail.
Since MIG is faster and consumes less time, it is more cost-effective. Additionally, MIG parts are available at a lower price than TIG.
MIG is easier to learn. Just like a glue gun, you have to pull the trigger to start or stop the weld. It requires only one hand and is the perfect option for beginners. On the other hand, TIG requires both hands and one-foot coordination to carry out different tasks. TIG also requires strict control over pressure, timing, and electric current.
MIG can weld thicker metals faster, whereas if you have to weld thin metals, TIG is the better option.
TIG welding is preferred by most as it gives clean finishing. It is usually used for artistic purposes for greater attractiveness.
Now that you know the difference between the two techniques, you can choose the one that best suits your welding materials.
