Gas Metal Arc Welding
Gas metal arc welding (GMAW) is also referred to as metal inert gas (MIG) welding. This welding process begins with the two metals to be joined being heated by a shielding gas flowing over the wire electrode. This method needs a constant voltage and direct-current power source and is the most frequent industrial welding technique, including plate and large bore pipe.
This type of welding is used in automotive work and construction and is one of the more common welding procedures.
Gas Tungsten Arc Welding
Gas tungsten arc welding (GTAW) is also known as tungsten inert gas (TIG) welding. TIG welding employs an electric arc as does MIG. TIG welding utilizes tungsten electrodes. Tungsten is a very strong metal that will not dissolve or burn away when welded. Fusion is the technique of using or not utilizing a filler substance in TIG welding.
Other gases, such as argon and helium, are also used. Aerospace and automotive are two industries that use GTAW/TIG welding.
Shielded Metal Arc Welding
Stick welding is a common name for shielded metal arc welding (SMAW). The stick uses an electric current to form an arc between the stick and the metals to be joined. It is essential that the welder be able to weld to a standard that allows their work to pass a destructive bend test. Shielded metal arc welding may be used to join carbon steel, alloys, stainless steel, cast iron, and ductile iron, as well as some non-ferrous metals such as nickel and copper.
Construction, maintenance and repair, underwater pipelines, and industrial fabrication are just a few of the places that stick welding is used.
Flux Cored Arc Welding
Flux cored arc welding (FCAW) is an alternative to shield welding. The semi-automatic arc weld is popular in construction since it has a fast-welding speed and is easily portable. Because of the many variables, this technique may be used for a variety of welding tasks. Variables often depend on the model of welder being used, and what type of wire was chosen for the application. Due to the potential of faster welding speeds, the newly joined metal cools quicker. Because the amount of smoke and fumes generated during the welding procedure, FCAW is best used outdoors or under industrial ventilation hoods.
This sort of welding is utilized for welding thicker metals and is also employed in the manufacturing industry.
