Welding is, in short, an art form. There are many different types of welding requiring different skill levels. Most beginners work with Mig welding or Arc welding, which are both relatively easy to work with. Tig welding, on the other hand, is a much more elegant style of welding that produces better welds and allows you to weld aluminium easier than other methods of welding. Tig welding should be left to the professionals who have the skills and resources necessary to purchase a Tig welder, which can cost thousands of Rands.

Mig Welding

1. The Mig in Mig welding is short for Metal Inert Gas. The gas is typically carbon dioxide or a combination of carbon dioxide and argon. The shielding gas is used to protect the area being welded from atmospheric gases, which if they came in contact with the weld area, would decrease the quality of the weld considerably. Mig welders work by automatically feeding an electrode at the press of a button shielded by the shielding gas. This is one of the easiest types of welding to learn and is perfect for beginners.
   

   Tig Welding

2. Tig welding is the type of welding professionals use, because it creates high-quality welds and has the ability to weld metals like aluminium and copper. Tig stands for tungsten inert gas. The tungsten is used in Tig welding to heat the welding area to join the two pieces of metal with or without a filler rod. The main difference between Tig welding and other types of welding is that Tig welding uses a tungsten electrode to heat the welding joint. Tungsten is nonconsumable, meaning that it doesn’t melt and become part of the welding joint like other types of welding. All you are doing with Tig welding is heating the welding joint with the tungsten. The drawback to Tig welding is the cost associated with obtaining a high-quality welder.
   

   Arc Welding

3. Arc welding, or what is referred to as stick welding, is popular due to its simplicity. Arc welding, unlike Mig and Tig welding, does not require a shielding gas, because as the electrode’s coating disintegrates, it gives off vapours that work like a shielding gas. This is beneficial for DIY work and for many companies, because it keeps costs low, as shielding gas is relatively expensive. All that is involved in Arc welding is an electrode that makes contact with the welding joint and fuses with the two pieces of metal. The Arc welder is simple, effective, and cheap.
