Carbon arc welding
From Wikipedia, the free encyclopedia
Carbon Arc Welding (CAW) is a process which produces coalescence of metals by heating them with an arc between a nonconsumable carbon (graphite) electrode and the work-piece. It was the first arc-welding process ever developed but is not used for many applications today, having been replaced by twin carbon arc welding and other variations.

[edit] Development
CAW could not have been created if not for the discovery of the electric arc by Sir Humphry Davy in 1800.
[edit] Variations
- Twin carbon arc welding (TCAW) in which the arc is established between two carbon electrodes
- Gas carbon arc welding (CAW-G) no longer has commercial significance
