8 Different Types of Welding Methods

When you start learning to weld, it may be overwhelming to take in the sheer amount of information available on the subject. It may be challenging to begin a fixing journey without knowing all the necessary information about the same.


Before starting your welding business, you need to know the types, processes, what and how it affects the metal, etc. But no matter which method you choose, the types of consumables used in it will affect its longevity and final output. So, using good quality parts like Hypertherm powermax 45 consumables and Hypertherm powermax 45xp parts is advisable. Thus, to guide you with the same, we have following article explaining the types of fixing processes:


MIG - Gas Metal Arc Welding (GMAW)

This is a simple form of fixing that is easy for any new welder to perform and practice. MIG stands for inert metal gas and it is also sometimes called gas metal arc fixing (GMAW). It is a quick welding process that involves the filler metal being fed through the wand. Here, the gas expels around it to shield it from outside elements. This means it is not great for outdoor use. But still, it is a versatile process and can be useful to weld many different types of metal with different thicknesses.


The filler metal is usually a consumable wire fed through a spool. This filler metal also works as an electrode. Whenever the tip of the wire creates an arc to the base metal, the wire melts and becomes filler metal and creates weld. Then the wire is continuously fed through the wand, allowing one to dial in your preferred speed. If done correctly, MIG welding produces a smooth and tight fix which is visually appealing.


TIG - Gas Tungsten Arc Welding (GTAW)

TIG welding is also known by the names of Heliarc and gas tungsten arc welding (GTAW). Here, the electrode is non-consumable and made of tungsten. It is one of those types of welding process that one can complete with no filler metal.


One just needs to use only the two metals that need welding together. A gas tank is essential with TIG welding for providing the constant flow of gas. This gas is necessary to protect the weld. This means it generally performs better indoors.


TIG welding is a precise process of welding. It creates visually appealing welds and does not require cleanup because there is no spatter. Due to these traits, it is best reserved for experienced welders.


Flux-Cored Arc Welding (FCAW)

This is similar to MIG welding. Just like in MIG fixing, in flux-cored arc welding, a wire that serves as the electrode and the wand is useful to feed the filler metal. Now let us come to the difference - for FCAW, the wire has a core of flux which creates a gas shield around the weld. This shield eliminates the need for an external gas supply.


Since it is a high-heat welding method, FCAW is better suited for thicker and heavier metals. It is often useful for heavy equipment repairs for this very reason. It is an efficient process that does not create much waste. Since there is no need for external gas, it is also low in cost. Though there will be a bit of slag left over which will need a bit of cleanup to make a beautifully finished weld.


Laser Beam Welding

This type of welding is useful on metals or thermoplastics. And as the name implies, this method involves using a laser as a heat source for creating the welds. One can use it on carbon steels, titanium, stainless steel, aluminum, and HSLA steels.


It easily automates with robotics and is therefore often useful in manufacturing, like in the automotive industry. And when we talk about the automotive industry, precision is a must. Thus, using quality parts like Hypertherm powermax 45xp parts can save you from messing up the final output.


Electron-Beam Welding

This is a method of welding where a high-velocity beam of electrons creates heat through kinetic energy by welding two materials together. Electron-beam welding is a highly sophisticated form of welding performed by the machine, usually in a vacuum.


Plasma Arc Welding

This welding method is similar to GTAW, but it uses a smaller arc than GTAW. This increases the precision of the weld. It also utilizes a different torch to achieve much lower temperatures. Gas is pressurized inside the wand to create plasma. The plasma then goes through the ionization process by making itself electrically conductive. This produces an incredibly high temperature that is capable of melting the base metals. This allows plasma arc welding to perform with no filler metal which is a similarity to TIG welding.


Atomic Hydrogen Welding

This is an extremely high-heat form of fixing, known as arc-atom welding. This welding method involves using hydrogen gas to shield two electrodes made of tungsten. This shield can reach temperatures above those of an acetylene torch. Also, it can perform with or without a filler metal.



This is an advanced method of welding used to join the thin edge of two metal plates together vertically. Instead of applying the fix to the outside of a joint, it will take place in between the edges of the two plates. Here, a consumable metal guide is useful to feed copper electrode wire. This later acts as filler metal.

When electricity generates through the metal, it creates an arc and then the weld begins. It begins at the bottom of the seam and it gradually moves up. This creates the weld in place of the seam as it goes. This is an automated process performed by machine.



Hopefully, now you have a basic understanding of the different methods of welding. One can perform some types easily through machines while some require expensive specialty equipment. Also, the quality of consumables that you use in your fixing method also affects your overall budget and result.

So, you should invest in quality consumables like Hypertherm powermax 45 consumables to secure the quality of outcome and save repair costs.
