Welds come in a variety of types. MIG, TIG, Stick Welding, and Arc Welding are the most common ones. However, in this article, we will be focusing on MIG and TIG.

MIG (Metal Inert Gas)

MIG, which stands for Metal Inert Gas, is also referred to as Gas Metal Arc Welding (GMAW). To do traditional MIG welding, you need the following:

• welding gun
• power source
• wire feed unit
• consumable welding electrode
• source of shielding gas

MIG welding parts are far more readily available and less expensive than TIG welding supplies. During MIG welding, the electrode wire forms an arc with the base metal being welded, melts, and fuses the two components. During this welding process, a gas bubble of protection is also created. This shields the weld from contaminants from the outside.

This type of weld is not recommended for 

• Outdoors
• Locations with moving air
• Damp areas

Due to the difficulty of "fusing" with MIG welding, it has been dubbed the "hot glue gun" of welding. Contrary to TIG, which actually fuses the two materials, the MIG electrode wire serves as an adhesive between the two materials. This means that you can join different types of metals using MIG welding. It is more frequently applied to: 

• Aluminium
• Steel
• Stainless steel
• Heavy-duty structural plates
• 26-gauge sheet metal

But, it is too weak for cast iron and too strong for thin aluminium. The ability to accelerate production and shorten lead times is a major advantage of MIG welding. 

MIG is also quite straightforward to learn and master in a few weeks. However, MIG welding occasionally results in weak and less ductile welds, which are common quality issues. To solve these issues, avoid materials that are too thick or too thin, along with impure or unclean materials.

TIG (Tungsten Inert Gas)

TIG, which stands for Tungsten Inert Gas, is also called Gas Tungsten Arc Welding (GTAW). Although TIG welding is difficult to master because of how hot it gets, welders have come up with some ingenious solutions over time. Some techniques include:

• Using minimum power
• Angle the torch appropriately
• Using the right type of tungsten

TIG welding is also done manually. For TIG welding, you will need:

• Welding torch
• Constant-current welding power supply
• An electrode of your choice
• Gas for shielding
• Grinder
• Filler metals

Additionally, you'll have to decide between hand control or pedal control, though most TIG welders use both hands. Since its electrode is non-consumable and constructed of tungsten, unlike MIG, you will eventually need to buy tungsten for maintenance after a few uses. 

With the exception of zinc and zinc alloys, TIG welding is typically utilised for nonferrous materials like:

• Aluminium
• Magnesium
• Nickel
• Titanium
• Copper

To weld different metals with TIG, a compatible filler metal is required. The result of TIG welding is a durable and high-quality fusion. Since the tungsten rod is thinner than a stick rod, TIG welds are delicate and precise. It can therefore result in some appealing joins.

The drawback of TIG is that it can be time-consuming and slow. Moreover, despite the fact that its electrode is non-consumable, the TIG machine is initially expensive. It should only be managed and operated by trained employees. 

MIG vs TIG

The materials you're working with will determine your best welding option. When done correctly, TIG welding may produce the best quality weld on any metal, but it fails to attach to thicker materials. Whereas MIG welding may be used on metals of any thickness, but it produces welds of lower quality and is mainly effective on steel and aluminium.

Despite having advantages and disadvantages of their own, TIG and MIG welding can both be the best option for your upcoming welding project. MIG welding is quicker and easier to do than TIG welding, but TIG welding provides you with better accuracy and a more attractive weld.

Which Welding Is The Strongest?

Due to the intense heat it generates and the delayed cooling rate that follows, TIG welding is frequently regarded as the strongest weld. Nevertheless, MIG is also a great option for the strongest type of weld because it may produce a strong joint.

The answer to this topic is fairly complex because the material to which a weld is applied determines its strength. There are three factors to consider when assessing a weld's strength which are:

• Length
• Size 
• Filler

As a result, there is no simple answer to the question, "What is the strongest sort of weld?" The strength of the weld relies on the material and the welder's expertise.
