In this guide, I am going to be talking about what welding is all about, and I’m going to be mentioning the many different types of welding.
Welding happens to be a fabrication process where two or more parts are actually fused with the use of heat, pressure or both forming a joint as the parts cool down. Welding is actually used on metals and thermoplastics. It is also something that can be used on wood. The completed welding joint may actually be called as a weldment.
A lot of materials actually required the use of specific processes and techniques and a number of which are actually considered unweldable according to The Welding Pro. This term is not actually found in dictionaries, but it is very useful and very descriptive in the world of engineering. The parts are actually jointed, and they are known as a parent material. The material which is added to help form the joint is called the filler or the consumable. The form of these materials may actually be referred to as a parent plate or a pipe, consumable electrode or a filler wire.
If you are someone who is thinking about pursuing a career in the world of engineering and welding, it is important that you identify the area that you would like to specialise in. There are more than 30 different kinds of the welding process, from oxy-fuel to more complex laser-beam welding practices. These varieties are actually broken down into four major groups.
The most well-known welding procedure categories are down below.
- Gas metal arc welding is also known as inert metal gas or MIG welding, and this process makes use of a thin wire as an electrode. The wire heats up as it is fed through the instrument that wells towards the building site. Shielding gas must actually be used to protect the weld from any contaminants in the air.
- Gas tungsten arc welding is the next one that I would like to talk about. This type of welding procedure is known as tungsten inert gas welding. It is commonly used to vent together some thin or even non-ferrous metals like aluminium, lead, nickel or even copper. It is commonly applied to bicycle or even aircraft manufacturing processes.
- Shielded metal arc welding is the third type. This type of welding relies on a manual technique which makes use of a consumable electrode which is coated in flux. This method also tends to be the most popular among home shop welders. It is more informally known as stick welding.
- Flux corded arc welding is very similar to MIG welding. This type of welding is very known for being an expensive and incredibly easy to learn.
