Graphite is a metal that conducts electricity and that is used to generate electrical arcs within furnaces is used to power arcs. The electrodes are durable, corrosion-resistant and made of the highest quality they are made of coal tar, petroleum coke and other materials. Graphite Electrode also has excellent heat and electrical conductivity. Graphite Electrode comes in a array of sizes, which can suit diverse applications and metals.
In the process of welding when the electrodes are placed into the weldment, and the flow of current flows via an arc that passes between the metals. The graphite-coated electrodes aids in conducting the electricity of the arc which is critical to an effective weld. Graphite also has its low content of impurities and good vibration resistance, and is able to withstand high temperatures. Graphite is a safe environmental friendly, non-toxic material that's highly efficient when it is used in the right application.
For an electrode to receive a label from the AWS as being a certain class, it needs to satisfy minimum performance requirements as well as tensile standards. A typical certificate indicates the electrode's class, as well as the results of tests that were utilized to establish that classification. The testing process is conducted under a standard procedure to guarantee consistency and reproducibility of the results. AWS certificates are issued by the AWS generally certificates are used by manufacturers to show that the class of an electrode has met the minimal requirements and can be used for their specific welding projects.
A few of the most commonly used graphite electrodes are:
HP Graphite Electrodes are made using the highest level of petroleum coke, and can operate under demanding conditions. They have a superior capacitance for carrying current compared to ordinary power (RP) graphite electrodes. HP graphite electrodes are suitable for industrial silicon furnaces, industrial yellow phosphorus corundum as well as other furnaces for smelting.
This RP graphite electrode class was made for general-purpose steel melting. This type of graphite is perfect for EAFs with a broad selection of capabilities for producing steel. This range of diameters is well balanced between the power of the material and its performance. It is a popular choice with steel melting industries around the world.
Specialty graphite electrodes are characterized by customized compositions, surface treatments or geometries designed to maximize performance in niche industrial applications. Specialized products are made available to suit specific furnace design, operation parameters, and steel quality requirements.
