AI overview

An electrode is a conductor—typically a metal rod or wire—used in welding and other electrical processes to carry electric current to the materials being worked on. In welding, the electrode melts and fuses with the base metal to join pieces together, making it essential for creating strong, permanent connections.

An electrode is an electrical conductor used to make contact with a nonmetallic part of a circuit (e.g. a semiconductor, an electrolyte, a vacuum or a gas). In electrochemical cells, electrodes are essential parts that can consist of a variety of materials (chemicals) depending on the type of cell. An electrode may be called either a cathode or anode according to the direction of the electric current, unrelated to the potential difference between electrodes.
