Various Types of Welding Procedures and When to Use Them

In case you're considering seeking a career in welding, it's essential to distinguish the territory you'd prefer to work in. There are more than 30 distinct sorts of welding measures, from oxy-fuel to more intricate laser bar rehearses. However, these assortments are commonly separated into four fundamental gatherings.

4 Main Types of Welding Processes

The most common welding procedure categories are as follows: gas metal arc welding (GMAW/MIG), gas tungsten arc welding (GTAW/TIG), shielded metal arc welding (SMAW), and flux-cored arc welding (FCAW).

In this post, we’ll detail the specifics assigned to each process and highlight the differences among them. Keep reading to learn all you need to know about the four main types of welding and what they’re used for.

Gas Metal Arc Welding (GMAW/MIG)

Also known as Metal Inert Gas or MIG welding, this process uses a thin wire as an electrode. The wire heats up as it is fed through the welding instrument and towards the welding site. Shielding gas must be used to protect the weld from contaminants in the air.

Typically, this comes in the form of carbon dioxide, oxygen, argon, or helium. This method is often used to work on metals such as stainless steel, copper, nickel, carbon steel, aluminum, and more. Of all the welding processes, this one is most popular across the construction and automotive industries.

Gas metal arc welding is believed to be one of the easier welding techniques to learn, making it a great focus for beginning welders. It also calls for minimal cleanup, offers high welding speeds and better control over thinner materials.

Some downsides associated with this type of welding process revolve around the costs of getting shielding gas along with an inability to weld thicker metals or perform vertical or overhead welding.

Shielded Metal Arc Welding (SMAW)

This sort of welding measure depends on a manual strategy utilizing a consumable cathode covered in transition. This technique will, in general, be generally well known among home-shop welders. This interaction is likewise more casually known as stick welding.

The moniker references the anode used to weld the metal, which comes as a "stick." Because protected metal curve welding requires insignificant gear, it's quite possibly the easiest measure around.

This sort of welding doesn't need protecting gas and can be performed outside the breeze or downpour. It likewise functions admirably on soil and corroded materials. All things considered, disadvantages do exist.

Stick welds don't commonly deliver the best quality items. They are inclined to porosity, breaks, and shallow infiltration. When all is said in done, stick welds are less strong than what different welding kinds will create.

Gas Tungsten Arc Welding (GTAW/TIG)

This sort of welding measure, otherwise called Tungsten Inert Gas or TIG welding, is ordinarily used for welding together thin and non-ferrous materials like aluminum, copper, lead, or nickel. It's usually applied to bike or airplane fabricating.

In contrast to different welding measures, TIG welding utilizes a non-consumable tungsten terminal to create the weld. In any case, you will require an outer gas supply, generally argon or a blend of argon and helium.

This is perhaps the most troublesome welding technique to dominate and creates the most excellent welds.

Since there is just a small region between the circular segment and the region being welded, it takes a colossal measure of exactness and expertise to finish. Welds conceived of this strategy are known to be very solid.

Flux Cored Arc Welding (FCAW)

Like MIG welding, motion-cored circular segment welding spins around a consistent wire feed measure. There are two separate cycles related to transition cored curve welding.

One includes the utilization of protecting gas while the other depends on self-protecting specialists delivered while fluxing specialists break down inside the wire.

This sort of welding is known for being modest and simple to learn. Like the MIG welding measure, it's an extraordinary path for starting welders to commence their professions in the field.

It likewise permits welders to play out their work outside (breezy conditions will not influence the weld). The self-loader curve gives a high welding rate and movability, making it a well-known cycle to utilize on development projects.
