If you want to enter the welding field, you need to know what type of welding you want to do in order to purchase the right type of equipment. Here is a basic rundown of what the four primary types of welding are, as well as the advantages of each type of welding. Use this guide to determine what type of welding equipment and training you'll need.
Resistance Spot Welding Or Spot Welding
This type of welding is very simple, and involves joining two different pieces of metal together through the flow of electrodes that are located on either side of the metals being welding together. The metal is joined together due to the resistance of the metal to the electrode flow.
This is a very simple type of welding that is primarily used for sheet metal work involving steel and stainless steel. It does not require any shielding gas and is relatively easy to learn.
Gas Tungsten Arc Welding
This type of welding is also referred to as GTAW, Tungsten Inert Gas Welding, and TIG Welding. With this type of welding, metals are joined together through the use of an arc that runs from the tungsten electrode on the welding equipment to the base metal that you are working with. Filler metal is occasionally used in this type of welding. A gas mixture is also used for the shielding process.
A variety of different metals can be welded together using this method, such as brass, titanium, stainless steel, copper, magnesium alloys and aluminum alloys.
This type of welding works best when trying to weld thin materials together and for very precise welding work. It requires a high level of practice and skill to perform correctly.
Shielded Metal Arc Welding
This type of welding often goes by either SMAW or stick welding. Metals are joined together by heating them up using an arc that is created between your welding tip and a covered metal electrode.
Shielded metal arc welding does not work well with really thin metals. This welding process also tends to create a lot of splatter and mess. It is relatively easy to learn.
This type of welding can be done outdoors. It can be used to weld together aluminum, cast iron, hard surfacing, steel, and stainless steel. It is the only type of welding that works effectively on cast iron.
Flux Cored Arc Welding
This type of welding often goes by its initials, FCAW. This type of welder looks more like a caulking gun than a welder. Out of the gun, a wire is fed out and an arc is made between the wire and welding machine. This melts the wire as you work.
FCAW welding works best with either stainless steel or steel. It is very easy to learn and to handle since the wire is continuously feed into the unit. It also works on dirty, old and rusty material. This type of welding can be done outside and in windy conditions, making it the ideal type of welding for quick construction repairs.
