= WELDING GLOSSARY =


 * Edge Flange Weld ** - A flange weld with two members flanged at the location of welding.


 * Edge Joint ** - A joint between the edges of two or more parallel or nearly parallel members.


 * Edge Preparation ** - The surface prepared on the edge of a member for welding.


 * Edge Weld ** - A weld in an edge point. Edge Weld is a weld where the edges of two pieces come together.


 * Education Documents** - This is a link to a collection of documents which will be useful to a Welding Instructor.


 * Effective length of weld ** - The length of weld throughout which the correctly proportioned cross-section exists. In a curved weld, it shall be measured along the axis of the weld.


 * Effective Throat ** - The minimum distance from the root of a weld to its face less any reinforcement. See also joint penetration.

 * Electrical Safety**


 * Electrode **


 * ** Arc welding electrode ** . A component of the Welding circuit through which current is conducted between the electrode holder and the arc. See arc welding.


 * ** Bare electrode. ** A filler metal electrode consisting of a single metal or alloy that has been produced into a wire, strip, or bar form and that has had no coating or covering applied to it other than that, which was incidental to its manufacture or preservation.


 * ** Carbon electrode ** . A non-filler material electrode used in arc welding or cutting, consisting of a


 * ** Carbon or graphite rod **, which may be coated with copper or other coatings.


 * ** Composite electrode ** . Any of a number of multicomponent filler metal electrodes in various physical forms such as stranded wires, tubes, and covered wire.


 * ** Covered electrode ** . A composite filler metal electrode consisting of a core of a bare electrode or metal-cored electrode to which a covering sufficient to provide a slag layer on the weld metal has been applied. The covering may contain materials providing such functions as shielding from the atmosphere, de-oxidation, and arc stabilization, and can serve as a source of metallic additions to the weld.


 * ** Flux cored electrode ** . A composition filler metal electrode consisting of a metal tube or other hollow configuration containing ingredients to provide such functions as shielding atmosphere, de-oxidation, arc stabilization and slag formation. Alloying materials may be included in the core. External shielding may or may not be used.


 * ** Metal-cored electrode ** . A composite filler metal electrode consisting of a metal tube or other hollow configuration containing alloying ingredients. Minor amounts of ingredients providing such functions as arc stabilization and fluxing of oxides may be included. External shielding gas may or may not be used.


 * ** Stranded electrode ** . A composite filler metal electrode consisting of stranded wires, which may mechanically enclose materials to improve properties, stabilize the arc or provide shielding.


 * ** Emissive electrode ** . A filler metal electrode consisting of a core of a bare electrode or a composite electrode to which a very light coating has been applied to produce a stable arc.


 * ** Lightly coated electrode ** . A filler metal electrode consisting of a metal wire with a light coating applied subsequent to the drawing operation, primarily for stabilizing the arc.


 * ** Metal electrode ** . A fillet or non-filler metal electrode, used in arc welding or cutting consisting of a metal wire or rod that has been manufactured by any method and that is either bare or covered with a suitable covering or coating.


 * ** Tungsten electrode ** . A non-filler metal electrode used in arc welding or cutting, made principally of tungsten.


 * Electrode Extension (GMAW, FCAW, SAW) - ** Electrode Extension **is t**he length of unmelted electrode, extending beyond the end of the contact tube during welding.


 * Electrode Holder ** - The "handle" portion of the arc welder that holds the electrode in place. (often referred to a as a stinger) (2**)** ** Electrode Holder ** . A device used for mechanically holding the electrode while conducting current to it. electrode lead. The electrical conductor between the source of arc welding current and the electrode holder.


 * Electroslag Welding (ESW) ** - Electroslag Welding is a welding process producing coalescence of metals with molten slag, which melts the filler metal and the surfaces of the work to be welded. The molten weld pool is shielded by this slag, which moves along the full cross-section of the joint as welding progresses. The process is initiated by an arc which heats the slag. The arc is then extinguished and the conductive slag is maintained in a molten condition by its resistance to electric current passing between the electrode and the work. See electroslag welding electrode and consumable guide Electroslag Welding.


 * Electroslag Welding Electrode ** - Electroslag welding electrode is a filler metal component of the welding circuit through which, current is conducted between the electrode guiding member and the molten slag. Note: Bare electrodes and composite electrodes as defined under “arc welding electrode” are used for Electroslag welding. A consumable guide may also be used as part of the Electroslag welding electrode system.


 * Exhaust Booth ** - A mechanically ventilated, semi-enclosed area in which airflow across the work area is used to remove fumes, gases, and material particles

Eye Injuries - Eye injuries account for one-quarter of all welding injuries, making them by far the most common injury for welders
