Types of Welding

When you think about Welder you might think that there is only one type of welding. This is a common idea because most people only see the finished product. However, there are many different types of welding that you might find interesting.

Really in a very basic sense of the term, welding is a way of taking metals and joining them together and gain a tight bond in the process. There are a variety of bonds that are done depending on the types of welding you use.

Types of welding fit under categories as listed here:

Gas welding
This type of Learn Welding creates a flame from a burning gas and this creates the welding heat that is needed. You will see this in the following types of welding:

TIG Welding and Everything you want to know about TIG Welding

The acronym TIG stands for Tungsten Inert Gas Arc Welding and the acronym GTAW stands for Gas Tungsten Arc Welding this is the same process but it is referred to by these two different names.

In the situation you will be Welding using an electric arc that generates the heat. You then have a tungsten non-consumable electrode that then produces the weld you are attempting to make.

One of the things that have to happen in this type of welding is that the particular metal that you are welding has to be shielded from contamination in the atmosphere or you will get a poor weld. Due to the point that was just mentioned, you will find that the area is shielded with an inert gas that is used with a filler metal where necessary.

This type of welding only works when you have a constant flow across the arc with an ionized gas that is called plasma. Plasma also has metal vapours within it. You will usually use GTAW if you have to weld thin metals like stainless steel, aluminium, magnesium or copper allows. GTAW also gives the person who is operating the welding process more control of the weld.

The meaning of this or conclusion is that this is a stronger weld that when compared to other welds has a higher quality than other types of TIG Welding . Many experts say that it is harder to learn, is complex and can be slower than other welding techniques.
