Often, the following types of coatings are used in the manufacture of electrodes: basic, rutile, mixed, acidic and cellulose. The breakdown of these figures goes like this: E indicates that its an electrode. Welding Cost1. Base Metal or Parent Metal: Base Metal or Parent Metal is one of the most important factors to be considered while selecting an electrode.a. Base metal mechanical properties: The mechanical properties especially the tensile strength of the electrode and that of the base metal should be similar or as close as possible.b. c. 2. Different Types of Welding Rods & Electrodes Welding Rods and Their Classification They are not all What are the 4 classifications of electrodes? | Welding Arc Welding Electrodes 1 In shield metal arc welding (SMAW) also known as stick, electrodes are consumable, which means that the electrode is consumed during its use and melts with the weld. The "E" in the classification stands for electrode. It is suitable for lighter welding applications. It is made of materials similar to the metal being welded. For example, a 1/8-inch 7018 rod runs well from 90 to 150 ampere, while a 3/16 inch 7018 - rod welds at currents up to 300 amperes.
