2. 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).

3. Gas metal arc welding - Wikipedia

   The most common electrode holder is a semiautomatic air-cooled holder. Compressed air circulates through it to maintain moderate temperatures. It is used with lower current levels for welding lap or butt joints. The second most common type of electrode holder is semiautomatic water-cooled, where the only difference is that water takes the place ...

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 ...

5. Gas tungsten arc welding - Wikipedia

   en.wikipedia.org/wiki/Gas_tungsten_arc_welding

   Gas tungsten arc welding (GTAW, also known as tungsten inert gas welding or TIG, and heliarc welding when helium is used) is an arc welding process that uses a non-consumable tungsten electrode to produce the weld. The weld area and electrode are protected from oxidation or other atmospheric contamination by an inert shielding gas (argon or ...

   Collectively, the defendants accused of raping Gisèle Pelicot are facing more than 600 years in jail [Reuters] They are young, old, burly, thin, black and white. Among them are firefighters ...

7. Shielded metal arc welding - Wikipedia

   en.wikipedia.org/wiki/Shielded_metal_arc_welding

   Though SMAW is almost exclusively a manual arc welding process, one notable process variation exists, known as gravity welding or gravity arc welding. It serves as an automated version of the traditional shielded metal arc welding process, employing an electrode holder attached to an inclined bar along the length of the weld.
