Arc welding
From GAWDAwiki
Arc welding is the fusion of two pieces of metal by an electric arc between the pieces being joined and an electrode that is guided along the joint between the pieces.

Types of Arc Welding
- Shielded metal arc welding
- Gas metal arc welding
- Flux cored arc welding
- Gas tungsten arc welding
- Submerged arc welding
Electrode Options
Consumable
Consumable electrode tips melt when an arc produces enough heat, and molten metal droplets detach and mix into the weld pool. Shielded metal arc welding, gas metal arc welding, flux cored arc welding and submerged arc welding are all forms of arc welding utilizing consumable electrodes.
Non-Consumable
When using non-consumable electrodes in arc welding, the electrodes do not melt. Rather, filler metal is melted into the joint from a separate rod or wire. Gas tungsten arc welding (GTAW) is a form of arc welding that utilizes non-consumable electrodes.
Power Supplies
Direct current and alternating current are both used in various forms of arc welding.[1]
