whats the meaning of tig?

Question

tig welding

Answer 1

TIG = Tungsten Inert Gas Welding.
TIG (or GTAW) welding is an arc welding process that uses and tungsten electrode and inert gas. It also makes the highest quality weld because the welder can carefully control the process, the inert gas prevents any oxygen infiltration in the weld, and the high standards of the welders insures a clean and tight weld. It is a slower and more difficult way to weld, but if you want the best weld possible then TIG is the way to go. Many automated factories use robots that can do TOG welding or plasma arc welding. That’s why it is the preferred weld to construct airplanes, construct nuclear waste burial caskets, to make fine welds, and to weld Non-Ferris metals like copper and aluminum.

According to Wikipedia: http://en.wikipedia.org/wiki/Tig_welding
"tungsten inert gas (TIG) welding, is an arc welding process that uses a nonconsumable tungsten electrode to produce the weld. The weld area is protected from atmospheric contamination by a shielding gas (usually an inert gas such as argon), and a filler metal is normally used, though some welds, known as autogenous welds, do not require it. A constant-current welding power supply produces energy which is conducted across the arc through a column of highly ionized gas and metal vapors known as a plasma."

“While the aerospace industry is one of the primary users of gas tungsten arc welding, the process is used in a number of other areas. Many industries use GTAW for welding thin workpieces, especially nonferrous metals. It is used extensively in the manufacture of space vehicles, and is also frequently employed to weld small-diameter, thin-wall tubing. In addition, GTAW is often used to make root or first pass welds for piping of various sizes. In maintenance and repair work, the process is commonly used to repair tools and dies, especially components made of aluminum and magnesium. Because the welds it produces are highly resistant to corrosion and cracking over long time periods, GTAW is the welding procedure of choice for critical welding operations like sealing spent nuclear fuel canisters before burial”

TIG Welding is also know as Gas tungsten arc welding (GTAW)

"GTAW is most commonly used to weld thin sections of stainless steel and light metals such as aluminum, magnesium, and copper alloys. The process grants the operator greater control over the weld than competing procedures such as shielded metal arc welding and gas metal arc welding, allowing for stronger, higher quality welds. However, GTAW is comparatively more complex and difficult to master, and furthermore, it is significantly slower than most other welding techniques. A related process, plasma arc welding, uses a slightly different welding torch to create a more focused welding arc and as a result is often automated."

"Among arc welding process, GTAW ranks the highest in terms of the quality of weld produced. Maximum quality is assured by maintaining the cleanliness of the operation."

"The equipment required for the gas tungsten arc welding operation includes a welding torch utilizing a nonconsumable tungsten electrode, a constant-current welding power supply, and a shielding gas source."

“Due to the absence of smoke in GTAW, the electric arc can seem brighter than in shielded metal arc welding, making operators especially susceptible to arc eye and skin irritations not unlike sunburn. Helmets with dark face plates are worn to prevent this exposure to ultraviolet light, and in recent years, new helmets often feature a liquid crystal-type face plate that self-darkens upon exposure to high amounts of UV light. Transparent welding curtains, made of a polyvinyl chloride plastic film, are often used to shield nearby workers and bystanders from exposure to the UV light from the electric arc.”
