Different Types Of Welding Explained

different types of welding

Welding is a process can be described as joining two different materials together, of which there are various different types of welding. The materials are commonly metal and both heat and pressure are used to help make the materials more malleable or soft so they can become joined or forged.

Welding dates back to the Middle Ages although the modern method that we know did not come about until the 19th-Century. In the modern world, welding is a skilled role and one that covers many different areas whereby welders utilise different methods that form part of the welding process. It’s a varied craft and one that now relies on skill and technology to undertake correctly. 

Welding is a technique that is commonly used by professionals and although it is not a new process, it requires the right tools and metals to ensure a successful job is completed. As metals are a solid materials, working with them can prove challenging but welding makes this possible and that means that welders can transform any piece into a shape or design. Despite this, welding is not something that anyone can pick up because it requires training, skill and an understanding of how each welding process works. 

To many, welding might seem as though it always consists of the same thing but this is not the case as there are more than 30 different types.  However, they are all unique and they are all used for certain purposes, so we are going to delve into the main types below and show you why they are used. 

Different Types of Welding and What are They Used for?

Arc Welding

The main process behind arc welding is using a device that uses an electric current that moves between two materials that are going to be welded together or joined. The name derives from the movement of an electric current, which commonly creates an arch when it moves between two materials. This form of welding is common as it known to be a cost-effective option. This still works by joining metal together but there are other forms arc welding that are used. This type of welding can include Submerged Arc Welding and Plasmas Transferred Arc Welding.

MIG (Metal Inert Gas) Welding

This type of welding is used when the materials being welded are fragile or delicate and have to be protected from the damaging effects of the welding process although this does not include the process of joining. It is also a method that is used should the job need to be completed quickly. During this process, a gas is used as this helps to create a protective shield for the weld metal, protecting it from natural elements such as oxygen. This makes it possible for the welder to weld at a continuous rate because the shielding ensures no damage is caused. Just like arc welding, there are many different forms of MIG welding such as Synergic MIG.

TIG (Tungsten Inert Gas) Welding

This form of welding is much like MIG welding although it uses a tungsten current form as opposed to a metal electrode that MIG uses. The use of tungsten is mainly down to the way in which can handle higher temperatures than many other materials before it reaches melting point. However, an additional filler is required and this is used inside the welding equipment. This is a form of welding that is commonly used in those industries that use stainless steel. Once again, this welding technique have a number of sub-categories and this can include the likes of Synergic TIG, Heavy TIG and Hot-Wire Automatic TIG.

At this point, you should now have a clearer understanding of what welding is and how the different types of welding are used. Of course, as we touched on, there are more than 30 different types and the methods above almost form an umbrella for the many different types of welding that fall within them.  Welding can be used for a whole range of applications but it requires expertise to ensure that it is performed correctly, safely and with precision. To achieve this, it requires the right personnel and the latest equipment.
