2. Gas tungsten arc welding - Wikipedia

   en.wikipedia.org/wiki/Gas_tungsten_arc_welding

   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.

3. Welding power supply - Wikipedia

   en.wikipedia.org/wiki/Welding_power_supply

   A welding power supply is a device that provides or modulates an electric current to perform arc welding. [1] There are multiple arc welding processes ranging from Shielded Metal Arc Welding (SMAW) to inert shielding gas like Gas metal arc welding (GMAW) or Gas tungsten arc welding (GTAW).

4. Arc welding - Wikipedia

   en.wikipedia.org/wiki/Arc_welding

   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 ...

6. Tungsten - Wikipedia

   en.wikipedia.org/wiki/Tungsten

   Tungsten's desirable properties such as resistance to high temperatures, its hardness and density, and its strengthening of alloys made it an important raw material for the arms industry, [54] [55] both as a constituent of weapons and equipment and employed in production itself, e.g., in tungsten carbide cutting tools for machining steel. Now ...

7. TIP TIG - Wikipedia

   en.wikipedia.org/wiki/TIP_TIG

   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.
