The Difference between MIG, TIG, and Stick


Welding has been around since the late nineteenth century. The art form began with stick welding and has since expanded into many different forms. Experimentation with welding on a large scale began with the British during World War I, building welded hulls for their warships. It continued into World War II, so that by the time the war ended, the industry was primed for a surge of new welders. Many former GIs were trained in the craft and could build faster and more efficiently than ever before.

From that age of innovation and expansion came three distinct forms of manufacture: MIG, TIG, and Stick. Do you know the difference? It is fine if you don’t, but it’s not fine if the welder you hire does not know the intricate differences. When you are looking for a Perth welding company, you should have a little bit of knowledge about the three kinds of welding so that you can make an informed decision about whom to hire.


Stick is the oldest form of welding. Technically, it is called shielded metal arc welding (SMAW). It is a manual arc welding technique that employs an electrode, the “stick,” which is covered with flux. The electrode carries the electric current that melts the metal pieces together. As the electrode carries the electricity and lays the weld, it disintegrates, which gives off vapour and produces slag to protect the weld.

This method is best when used for iron and steel, but it is possible to weld nickel, copper, and aluminium this way. It is most commonly used for heavy steel fabrication and industrial applications.


Metal inert gas welding is also known as MIG. A wire electrode passes an electric arc to the metal to be melted and joined. The welding gun also feeds a shielding gas that protects the weld from outside contaminants.

MIG was originally invented for non-ferrous materials such as aluminium but has come into use for other metals as well. It is one of the fastest welding processes, but it does not work as well outdoors or in windy areas because it requires a shielding gas.


TIG is similar to MIG except the metal electrode is not consumable. TIG stands for Tungsten Inert Gas, meaning that the electrode is made of tungsten, and the welding gun releases an inert shielding gas. This gas is usually helium or argon because they are not reactive to electricity.

TIG’s main use is joining stainless steel in thin sections and non-ferrous metals. TIG provides the greatest control over the weld but also requires a higher level of skill than some of the other processes. Also, it is much slower than the other processes, so it might only be useful for smaller jobs. However, the welds from a TIG process are some of the cleanest and most attractive. To recreate the look with other processes, welders might have to grind or buff the finished product.

As you can see, the different welding processes are slightly varied and appropriate for different situations. When you are hiring a welding company, it is good to be a little bit knowledgeable so that you can make the best possible decision.
