What types of welding are there?

In the context of welders, one often speaks of different professional groups. But that is not correct, because it is primarily the welding processes that set them apart from the others.

Basically, there is a multitude of different types, with four welding processes now being the most widely represented. We are talking about:

  • Gas welding
  • TIG welding (tungsten inert gas welding)
  • Manual arc welding (E-welding)
  • MAG welding (metal active gas welding)

These four types have now clearly stood out from the others and are today's solutions. This blog post will thematically deal with the different types of welding and their areas of application.

1. Gas welding

Gas welding is one of the older processes, but it still has its raison d'etre here and there. This process is characterized by the fact that the weld seam is heated and consequently melted.

The autogenous welding device acts as a heat source and is jointly responsible for ensuring that the melt is protected from oxygen and oxidation. Gas welding is mainly represented in the craft. Gas welders are often used to supply gas and water pipes.

But that's not all, gas welding is still very popular in the field of external assembly or in general pipeline construction.

2. TIG welding

Tungsten inert gas welding is an integral part of welding and cannot be imagined without it. The arc is essential in this welding process and the defining feature, as it is positioned between the workpiece and the well-known tungsten electrode.

The tungsten electrode reaches a high melting point and consequently does not melt during the process. This welding process uses an additional material that is held in the arc and melts together when the workpiece is welded.

Usually inert gases are used, which bypasses a chemical reaction with the air. Metalworking is one of the typical areas of application for TIG welding. But TIG welders are also always in demand in apparatus construction, tank construction or the very general pipeline construction.

3. Manual arc welding

Arc welding also uses the arc that is used between the workpiece and the electrode. In contrast to TIG welding, the position in this process is such that the electrode serves as a filler material and consequently melts.

In addition, other electrodes are used - we are talking about stick electrodes. These have a casing and this in turn ensures that appropriate protective gases are emitted.

This protects the melt from chemical reaction with the air. Compared to the other processes, the process known as electric welding is one of the oldest in the industry. Typical areas of application are in pipeline construction, but manual arc welding is also often used in steel and bridge construction.

4. MAG welding

MAG welding (metal active gas welding) uses a mixture of different active gases and is a process that is often used in metal construction.

The gases mentioned influence the quality of the weld seam and ensure that there is no chemical reaction. In addition to metal construction, MAG welding is also used in vehicle and mechanical engineering.

All four types of welding are essential for the economy

Ultimately, it can be said that the four species presented in this article have long been an integral part. Even though industrial welding outstrips many, manual electrode welding is still considered to be indispensable.

Anyone who is faced with choosing the right welding process should deal with the topic in peace. A hasty decision can result in tailor-made changes for the welder himself. But that's not all, because companies too have to think carefully about which process should be used before realizing a project.

The selection of the welding process chosen for the respective project determines how successful the production looks - especially since there are also economic aspects and these must also be taken into account.
