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?

Plasma 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. The plasma arc welding is common as it known to be a cost-effective option. This still works by a joint 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 Welding (Metal Inert Gas)

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 Welding (Tungsten Inert Gas)

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.

Welding Types to Use for the Job

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.

What Is Spiral Welding?

In a nutshell spiral welding is the process by which a cylindrical object has a new surface welded onto it whilst the object is being turned on a rotary turn table.

However to understand this fully we first need to look at what exactly welding is, what are some of the uses of this specific process of spiral welding and what are the advantages of spiral welding?

What Is Welding?

Spiral WeldingWelding is the process by which two materials, usually metals or thermoplastics, are permanently bonded with each other. This result is created by heat being applied to both materials so that the areas of them which are to be joined melts, mixes and then solidifies to form a permanent bond. In many cases of welding a filler material is also introduced to the join which then also melts and mixes with those of the materials being welded together. In these cases this mixture of materials when solidified forms a joint that is often stronger than the original base material.

However the process of spiral welding introduces another material to the original (the substrate) in order to form a strong tough and durable overlay, rather than attempting to join it to a third material. The Spiral Welding process is applied in an inert argon gas atmosphere to prevent oxidation during the welding.

Uses of Spiral Welding

As mentioned above, spiral welding is the process of coating a cylindrical object with another material to renovate or recondition it. It can be used to rebuild damage from wear, erosion, corrosion or cracking, or to increase the dimension of the object to match it up to another part or matching component. Check here It can be used on a wide variety of objects but is most commonly used on pipework and manufacturing shafts.

Advantages of Spiral Welding

There are many advantages to using spiral welding rather than other welding techniques. These can include:

  • Repairing a component via the spiral welding process is often cheaper than buying a new component and results in less possible downtime. Find here more about 619 Roofing of San Diego.
  • Faster turnaround time than manufacturing an entirely new component.
  • Can result in a higher strength component that the original, depending on the choice of coating material.
  • Spiral welding eliminates possible distortion of the substrate due to unbalanced stresses from normal welding processes.
