Gas Tungsten Arc Welding— Gas tungsten arc welding (GTAW) uses a nonconsumable tungsten electrode that creates an arc between the electrode and the weld pool. An inert shielding gas is used in the process at no applied pressure. Argon is most commonly used as the shielding gas, and the process may be employed with or without the addition of filler metal. An illustration of the gas tungsten arc welding process, also referred to as nonconsumable electrode welding, and tungsten inert gas (TIG) welding.
Advantages of GTAW include its versatility, low equipment costs, control, and weld quality. It is widely used for the welding of light gauge stainless steel and aluminum and root passes in pipe butt joints. The GTAW process can easily be set up as an automated process.
Another positive attribute of GTAW is the very low fume formation rate (FFR). The filler wire is fed and melted into the weld pool allowing a lower FFR. This procedure is different from other processes that require the fill material to pass through the arc. Since filler is fed directly to the weld pool, operating variables have little effect on the FFR.
Disadvantages of GTAW are its low speed and deposition rate which utilizes hot or cold wire feed and high heat input efficiency. By using shielding gas, these problems can be overcome. The GTAW weld zone is also difficult to shield properly in drafty environments.
Welding rod fumes contain manganese a deadly neurotoxin that inhibits the brain’s ability to regulate physical motion. Men and women exposed to these manganese fumes develop Parkinsonian symptoms at the age of 46 as opposed to 66 and suffer for the rest of their life. Manganism is an induced form of Parkinson’s Disease.
