What is inert gas welding?
Inert gases or noble gases are gaseous elements in the helium group of periodic tables that are considered chemically unreactive. These gases that do not form chemical compounds are helium, neon, argon, krypton, xenon and radon. Inert gas welding is a welding process that uses inert gas to protect the weld during the welding process.
During the welding process, an electric arc between the electrode on the welding device and the workpiece is hit. This arc creates heat that connects the edges of connected metal pieces, as well as any consumer electrode that forms a weld joint. The gases used in inert gas welding include Argon, Helium, Carbon Dioxide or a combination of gases such as Argon and Oxygen. A electrical arch is formed between the electrode and the sheet. The inert gas is surrounded by welding protection from oxidation. This method works with carbon steel, low alloy steel, stainless steel and mostly aluminum, copper and zinc alloys. MIG welding can be pOut to weld metals with thicknesses of two tenths to a quarter of inches (0.5 mm to 6.3 mm).
Tungsten gas welding (TIG) uses an inconsisible electrode made from tungsten. Unlike MIG welding, tungsten welding does not require filling material. This method can be used on the same metals as MIG welding, but does better work in welding different metals together. One of the advantages of TIG welding is that it can connect with pieces as thin as five hundredths of the inch (0.125 mm).
The location and cosmetic meaning of the weld will help determine which form of inert gas welding it uses for a specific application. MiG welding is cheaper and does not require a high level of expertise from the operator. However, Mysier is Messier because of the use of consumer electrode or filling material. If the weld is in an area that is visible, MiG welding is generally not recommended because the wayIt is a lot of spraying that needs to be grinded or filled.
TIG welding is a bit more expensive than MiG welding, but it is a recommended method if the appearance is important. There is no spray during the weld, because the inconsistent tungsten electrode does not use any filling material. This method requires a higher level of training and expertise of the operator. Argon is the most commonly used gas for TIG welding.
gas welding has been used since the 1840s and is faster than traditional welding methods. It can produce cleaner, longer continuous welds, especially with thinner materials. One of the disadvantage of this form of welding is that the device is less portable and more expensive than other gas welders. Another restriction is that Inside welding must be made and not in an open space where the wind can interfere with the protection gas shield.
