2. Flux-cored arc welding - Wikipedia

   en.wikipedia.org/wiki/Flux-cored_arc_welding

   Flux-cored arc welding (FCAW or FCA) is a semi-automatic or automatic arc welding process. FCAW requires a continuously-fed consumable tubular electrode containing a flux and a constant- voltage or, less commonly, a constant- current welding power supply .

3. Gas metal arc welding - Wikipedia

   en.wikipedia.org/wiki/Gas_metal_arc_welding

   DCEP, or DC Electrode Positive, makes the welding wire into the positively-charged anode, which is the hotter side of the arc. [58] Provided that it is switchable from DCEN to DCEP, a gas-shielded wire-feed machine may also be used for flux-cored wire. [citation needed]

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. Electroslag welding - Wikipedia

   en.wikipedia.org/wiki/Electroslag_welding

   Electroslag welding (ESW) is a highly productive, single pass welding process for thick (greater than 25 mm up to about 300 mm) materials in a vertical or close to vertical position. (ESW) is similar to electrogas welding , but the main difference is the arc starts in a different location.

7. Electrogas welding - Wikipedia

   en.wikipedia.org/wiki/Electrogas_welding

   The weld area is protected from atmospheric contamination by a separate shielding gas, or by the gas produced by the disintegration of a flux-cored electrode wire. The electrode is guided into the weld area by either a consumable electrode guide tube, like the one used in electroslag welding, or a moving head. When the consumable guide tube is ...
