Definition - What does Arc Welding mean?
Arc welding is a family of welding processes. Arc welding creates a weld by heating materials with an electrical arc until they coalesce. Arc welding can be performed with or without pressure and with or without adding joint filler materials. Many different types of materials can be welded by an arc welding process, assuming they are fair conductors of electricity.
The thermal cycling a material undergoes as a result of arc welding can increase the risk of several types of corrosion.
Corrosionpedia explains Arc Welding
Arc welding is a very popular family of welding processes, which includes:
- Shielded metal arc welding (SMAW) - Involves a rod of material that is covered in a flux. The rod serves as an electrode in the electrical circuit.
- Gas metal arc welding (GMAW) - Similar to SMAW, except that it uses a bare, solid wire electrode that is continuously fed into the weld pool.
- Gas tungsten arc welding (GTAW) - Uses a tungsten rod as an electrode. Filler metal is added separately from the electrical arc, if it is used at all.
There are many different types of arc welding in addition the ones listed here.
