“What kind of welder do I need” is a common question that we get a lot, and here, in this article, we will try to educate you with the descriptions of different types of welding. After that, you will match your requirements and know which model is necessary for the job.

A lot of guys may try to convince you to use one kind of welder for a different kind of job, stating that they are the same. We recommend you not to listen to those ideas and stick to the one that is made for its specific task.

Types Of Welding

We came to know about seven different types of welding used across the world for different types of requirements. Depending on the material to be welded along with some other factors, the required type changes.

What Kind Of Welder Do I Need

MIG – Gas Metal Arc Welding (GMAW)

An electric arc is formed while doing MIG welding, between the consumable wire electrode and the workpiece metal. As a result, heat is created, the metal of that specific point melts and joins together while gas from the welding gun protects it from the air.

TIG – Gas Tungsten Arc Welding (GTAW)

This is almost like the MIG welding, but argon or helium is used to protect gas from oxidation. As non-consumable tungsten electrodes are used, it is called gas tungsten arc welding or GTAW.

Stick – Shielded Metal Arc Welding (SMAW)

Informally, professionals know this as stick welding that includes a consumable stick with flux to be melted on the piece joining them. The flux of the stick produces gas that protects the weld from air contamination, making it stronger.

Flux-Cored Arc Welding (FCAW)

This is almost like the SMAW that we described above but better because of its automatic or semi-automatic process. A spendable tubular electrode that contains a flux and a constant-voltage is continuously fed, and it will let you quickly weld large pieces.

Electron-beam welding (EBW)

EBM is the fusion process that allows metal pieces to join using a beam of high-velocity electrons. It makes the workpieces melt and flow together, joining strongly and reliably. You know that the kinetic energy of the particles is used here and is responsible for melting the metal in the first place.

Atomic Hydrogen Welding (AHW)

AHW is another arc welding process that uses two tungsten electrodes, and an arc is created between the two electrodes in a shielding environment created with hydrogen gas. As the arc breaks up the hydrogen molecule in the atmosphere, it can create a tremendous amount of heat to melt some of the most hardened metals on earth.

Plasma Arc Welding

After comparing the process of Plasma Arc Welding and GTAW, you will find a lot of similarities, but the main difference is that the plasma arc can be separated from the shielding gas envelope allowing it to reach a very high temperature.

This is the main part of the article that you can’t skip because you will get to know the type you would require for your job. As you have already seen a little about those types, let’s talk about where they are applied.

MIG – Gas Metal Arc Welding (GMAW)

Professionals rely on MIG for welding aluminum and other non-ferrous metals, and it is the most common industrial welding process for its hassle-free features.

TIG – Gas Tungsten Arc Welding (GTAW)

Throughout the industry, TIG welding is widely accessible to weld thin sections of stainless steel and non-ferrous metals. For example, such non-ferrous metals include aluminum, magnesium, and copper alloys.

Stick – Shielded Metal Arc Welding (SMAW)

The simplicity of this welding process remains the most popular welding for beginners and in the repair industry. Also, constructions, including heavy steel structures, use this method due to its effectiveness.

Flux-Cored Arc Welding (FCAW)

The applications of FCAW are the same as SMAW, but this one is preferred in large industrial projects due to its fast capabilities.

Electron-beam welding (EBW)

Where there is a vacuum condition, and you need to weld pieces, EBM is the welding process professionals use to prevent dissipation of the electron beam.

Atomic Hydrogen Welding (AHW)

If you research a bit, you will know that the Atomic Hydrogen Welding can produce heat up to 4000-degree Celsius, which can melt and weld tungsten, one of the most refractory metals.

Plasma Arc Welding

Due to its capability of reaching very high temperatures that can be up to 50000-degree Fahrenheit, it is widely used to both welds and precisely cut thin and thick metals in industrial setups. Another perfect case for using PAW is to spray a coat of hardening metal on another metal with its properties.

Frequently Asked Questions

A lot of people ask a lot of questions on what kind of welder do I need and let’s answer some of the most frequent ones below to clear some ideas.

Can I run a welder at home?

If you are a learner and want to try welding yourself, you can try some low-power welder at home without having any issue.

Does welding use a lot of electricity?

The amount of electricity to weld depends on the type of welding, and it can be very high for large submerged arc units and low for small MIG welders.

How many watts do I need to run a welder?

The watt calculation for welders also depends on the size of the machine, and you will find the value in the manual of the welder.
