Discovering the world of welding

Welding is a process by which two or more objects are permanently joined together. The advantage here is that no intermediate tools are needed for joining. This is because the connection is made at the atomic level. There are different types of welding. Let's find out through this article.

Flame welding

This is the most widely used and indeed the best known welding technique. The process is very simple. Indeed, you have to create a flame with a torch and gas. This gas can be propane, butane or methane. These are gases that act as fuel. However, you will also need an oxidising gas, usually oxygen or natural hydrogen. Thus, the mixture of these two types of gas will produce the flame. The higher temperature flame is produced by a mixture of acetylene and oxygen. Read the contents of this link for more details.

Tungsten Inert Gas or TIG welding

This technique requires the use of an electric arc, an electrode made of tungsten and neutral gas. The main role of the neutral gas is to protect the arc and the electrode. This welding is generally used when fine, quality work is required.

Plasma welding

This welding is even more advanced than the previous ones. Here an electric arc and a plasma jet are also used. Indeed, this plasma jet is obtained as a result of the formation of the electric arc between a non-fusible electrode and the object to be welded. In addition to argon, this welding method requires the use of another type of gas called ring gas. This can be, for example, helium. It should also be noted that the electrode is protected by a copper nozzle which must frequently be cooled with water in order to avoid the risk of melting. You now know enough about welding. Pay attention to the type of welding used by the professionals, taking into account your needs.
