Welding is the process of fusing metal sheets together, so they take on a completely different shape and purpose. However, it is not as simple as just heating up the metal so it becomes molten or malleable, as there are several different types of welding techniques.
Shielded Metal Arc Welding
This involves the use of a stick over the metal, with an electric current running between the two metals to be joined. This forms an arc of electricity and is regularly used on carbon steel, alloyed steels, stainless steels, ductile iron and cast iron. It is also popular as it can be used on a few non-ferrous metals like nickel and copper.
However, it is not regularly used on aluminium, which is easily malleable and has high thermal and electricity conductivity.
Gas Tungsten Arc Welding
Another arc-welding process that requires the use of a fixed consumable tungsten electrode.
It is particularly used for non-ferrous metals or stainless steel that is thick and, otherwise, difficult to mould.
Gas Metal Arc Welding or Metal Inert Gas
Gas metal arc welding, otherwise known as metal inert gas welding, involves a wire electrode with a shielding gas running inside it. This heats up the two metals that need to be joined and fuses them together.
It is perhaps the most popular form of welding in industrial processes.
Flux Cored Arc Welding
Flux cored arc welding uses a semi-automatic arc weld, with gas travelling through tubular electrode towards the metals.
This technique is incredibly popular for use in construction projects, as it is fast and portable, and can operate at different angles and voltages.
