TIP TIG welding torch. TIP TIG is a subset of gas tungsten arc welding (GTAW), using a mechanism called filler wire agitation to enhance molten weld pool dynamics. This agitation has been found to enhance the weld puddle fluidity and release evolving gases, reducing the chances of inclusions and porosity, and also separate impurities.
GTAW weld area. Manual gas tungsten arc welding is a relatively difficult welding method, due to the coordination required by the welder. Similar to torch welding, GTAW normally requires two hands, since most applications require that the welder manually feed a filler metal into the weld area with one hand while manipulating the welding torch in the other.
Gas tungsten arc welding (GTAW), or tungsten/inert-gas (TIG) welding, is a manual welding process that uses a non-consumable electrode made of tungsten, an inert or semi-inert gas mixture, and a separate filler material. Especially useful for welding thin materials, this method is characterized by a stable arc and high quality welds, but it ...
After striking the arc, welding can be carried out in the same way as in TIG welding process. An AC supply is recommended for TCAW. [2]: 75 In case a DC supply is used, the positive electrode will disintegrate and consume at a much faster rate as compared to negative electrode, because two-thirds of the total heat is generated at the positive ...

Submerged arc welding (SAW) is a common arc welding process. The first SAW patent was taken out in 1935.

The DC arc largely applicable to ferrous metals, benefits from using 2% thoriated tungsten (or 2% ceriated tungsten, an alternative to the radiological concerns of Thorium), while nonferrous metals such as aluminum and magnesium requiring AC current, are performed best with pure tungsten allowing the tip to melt into an enlarged balled surface ...
Current is then passed between the two edges of the steel to heat the steel to a point at which the edges are forced together to form a bond without the use of welding filler material. Initially this manufacturing process used low frequency AC current to heat the edges. This low frequency process was used from the 1920s until 1970.
