Welding is a process of fusing metals with heat to create a joint. There are four main types of welding: shielded metal arc or MIG welding, gas tungsten arc or TIG welding, plasma cutting, and laser cutting.
Each type of weld has its own varying advantages and disadvantages as well as uses in different industries.
MIG welding is the most common type - it consists of the use of an electric current to strike the end of an electrode with a consumable wire that sends out a stream of molten metal that can be shaped into whatever you want. It's also applied to aluminum alloys and stainless steel.
MIG welding does not require a pre-welded connection point, which makes it more versatile than other types. It's also easier for an inexperienced
There are three key benefits that we can get from welding.
1. Welding provides a way to join metal and other materials together without the need for adhesives and fasteners, making it easy to repair objects.
2. Welding is also very economical - it uses less energy than cutting, drilling, or riveting to create joints with your metal pieces
3. Welds are stronger than most mechanical joints made by traditional methods
The six processes of welding are:
1) Planning and setting up the work, 2) Welding in preparation for joint, 3) Welding joint in preparation for joint, 4) Welding joint (filler metal), 5) Cooling down and removing oxidation products from filler metal, 6) Cleaning and adjusting the work.
