In workersâ compensation, the experience modification is the critical component of the premium calculation. Even so, it is. often misunderstood by the employers who receive these experience ratings.
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 air). The word was coined by William Whewell at the request of the scientist Michael Faraday from the Greek words elektron, meaning amber (from which the word electricity is derived), and hodos, a way.
Electrode: A part of the electical circuit (Normally positive terminal is connected to it) Filler metal: Metallic wire used to fill the gap between the base metals to be joined. It need not be a part of the electrical circuit. Welding Rod: A colloquial name of electodes/filler metal used in SMAW process. An electrode could be either consumable or non-consumable. (i.e) during welding, the metal reqd to fill the gap could be provided by the electrode itself (SMAW, GMAW,SAW processes). In GTAW process, the tungsten electode is non-consumable & thats why it is called as autogenous welding.
