Welding is the process of fusing two pieces of metal together. There are many types of welding which can be used to fix two pieces of metal together, therefore the correct method needs to be chosen based on the work being carried out.
Some welding processes can be done by machine but some still require the use of a skilled professional welder. This article will discuss the different types of welding and what applications they are used for. Welders in industry are required to be qualified to certain standards, this is often required for coded welding.
MIG (Metal Inert Gas) Welding
This is the process of combining two pieces of metal together using a wire connected to an electrical current. A shielding gas is used when the two pieces of metal are being welded together to prevent the weld being contaminated. This is the most common type of welding in industry today. Mild steel, stainless-steel and aluminium are all metals which can be fused together using the MIG welding process.
Arc welding is often referred to as stick welding due to how basic the process is. This type of welding is often used in the construction of steel structures and industrial fabrication, stick welding can also be used in manufacturing and repair work.
TIG (Tungsten Inert Gas) Welding
A tungsten electrode is used in the TIG welding process, this electrode is non-consumable. This type of welding takes a huge amount of skill to complete properly as it is a complex process. TIG welding is used when a superior finish is needed without the use of excessive grinding or sanding.
In conclusion these are the main types of welding used in industry today and they cover a wide range of jobs.
