Welding techniques: the most common ones

We have already introduced a guide to the types of welding in the past. Here instead we want to talk more specifically about the three most common and used welding techniques.

We will talk about about three processes that are autogenous welding techniques. Autogenous welding is a welding in which the base material melts and takes part in the final composition of the joint.


The 3 welding techniques are:

  • electrode welding
  • continuous wire welding (MIG/MAG)
  • TIG welding

Electrode welding

It is the most common welding technique, because it is cheap and simple. Even those who are not a professional welder can use this technique. But be careful: before getting good results, you must do some practice.

Continuous wire welding

This technique is more expensive and a little more complex. This is why it is mainly used on a professional level. The MIG (Metal-arc Inert Gas) or MAG (Metal-arc Active Gas) welding technique is very popular because it can be used semi-automatically and, not being particularly expensive, is also used by small and medium-sized enterprises.

TIG welding

It is the least common of these techniques, but it is the most accurate. It is used professionally to achieve beautiful and clean welds. The resulting bead is very regular and appears to be made up of overlapping coins.

Here are the most common welding processes. As you read, welding techniques are complex, you need to know all the materials well (because each material reacts differently). This is why it is always better to contact and get advices by professionals.

Here at GFB Fucina Meccanica we work with iron and metals and we are specialized in pipelines and in the metal carpentry sector in general. Contact us for more information on welding techniques and which one is right for you.
