What is the specification of welding electrode?
The number E6010 – indicates an arc welding electrode with minimum stress relieved tensile strength of 60,000 psi; is used in all positions, and reverse polarity direct current is required….
| Digit | Coating | Weld Current |
|---|---|---|
| 0 | * | * |
| 1 | Cellulose Potassium | ac, dcrp, dcsp |
| 2 | Titania sodium | ac, dcsp |
| 3 | Titania potassium | ac, dcsp, dcrp |
What does E6011 mean?
E6011 – all-position rod that is a preferred choice for maintenance work, or where metal is rusted and/or dirty. E7018 – all-position rod that is the preferred choice for Ironworkers and erectors due to its greater tensile strength and versatility. E7024 – A rod that can only be used in horizontal and flat positions.
What is E6010 welding rod used for?
E6010 is used for deep penetration welding, while E 7018 is used for welding metal that tends to crack, producing quality welds with excellent toughness and high ductility. Usually, both electrodes are used together in various industrial applications (pipelines welding, storage tanks, etc.).
What is electrode in welding?
An electrode is a coated metal wire. 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. In Tungsten Inert Gas welding (TIG) electrodes are non-consumable, so they don’t melt and become part of the weld.
What is electrode size?
Generally the size of the electrode that should be used depends on the thickness of the part to be welded. For thin metals the electrode is only slightly larger than the metal to be welded. For example if a plate is of 2.0 mm thick the electrode of 2.5 mm should be used.
What does 7018 mean?
The 7018 Welding Rod The “E” in E7018 electrode indicates a tool used for an arc-welding process. The 70 means it makes welds that are very strong (70,000 psi). The 18 means two things: The “1” means the electrode can be used in any position, and the “18” means low hydrogen and usually DC current.
What is the difference between E6010 and E6011?
The main difference between the two is with the recommended welding polarity. E6010 electrodes are intended for direct current (DC) only. While E6011 electrodes can be used on alternating current (AC), as well as DC.
How are mild steel electrodes used in welding?
Description: Mild Steel Electrodes A versatile, deep penetrating steel electrode with smooth, stable arc characteristics. It’s used for the welding of mild steels, galvanized and some low alloy steels. The coating produces a forceful, spray-type arc, resulting in deep penetrating welds.
What can a 6013 electrode be used for?
APPLICATIONS: 6013 electrode is commonly used for automobile bodies, truck frames and bodies, ornamental iron, metal furniture, farm implementations, machinery guards, storage tanks, or wherever appearance is important or desirable.
What’s the difference between E6012 and E6013 electrodes?
E6013 [E4313] electrodes, is very similar to the E6012 [E4312] electrodes but E6013 is having distinct differences in coating, slag formation & welding polarity. E6013 electrodes have low penetrating power, fast freezing slag and this may result in incomplete penetration in fillet welded joints.
What is the flux coating of the E6013 electrode?
E6013 electrode flux coating contains rutile, cellulose, ferromanganese, potassium silicate as a binder, and other siliceous materials. The potassium compounds permit the electrodes to operate with ac at low amperages and low open-circuit voltages. During the burning of coating, the flux coating of E6013 will mainly create carbon dioxide (CO 2 ).
