Graphite electrode for air-arc cutting, used for air-arc cutting of steel and copper welding, cutting rivets, removing profits and casting defects, gouging electric tacks and welds at a current of up to 1000 A.

Carbon electrodes are produced by pressing and subsequent heat treatment of coal powder in the form of round and rectangular rods.

For air-arc cutting, round rods (VDK grades) with a diameter of 6, 8, 10, 12 mm and a length of 300 mm are produced, as well as flat rods of the VDP brand, with a cross section of 5x12 and 5X18 mm and a length of 350 mm. For welding, round rods of the SK brand are produced with a diameter of 4-18 mm and a length of 250 mm or more. To improve the thermophysical properties and greater resistance, carbon rods are subjected to graphitization by heat treatment at a temperature of 2600 °C. Graphitization reduces the ohmic resistance of the electrodes by 4 times, so they heat up less, oxidize (burn out) less and are used at a higher current.

When using non-consumable electrodes, one should adhere to technological rules that ensure high-quality welding or cutting, as well as less wear of the electrode during operation. Welding and cutting with a carbon electrode, as well as plasma cutting, are only possible with direct current of direct polarity. It is also necessary to follow technological recommendations for sharpening the end of the electrode and fixing it.

The main thing

View by manufacturing method

Carbon electrodes are produced by pressing and subsequent heat treatment of carbon powder in the form of rods of round and rectangular cross-section.

Chemical composition

The chemical composition of graphite is not pure. Ash is present in large quantities (up to 10-20%), consisting of various components (FeO, SiO2, Al2O3, MgO, P2O5, CuO, CaO, etc.), gases (up to 2%) and bitumen, and sometimes water.

Type by purpose

Graphite electrode for air-arc cutting, used for air-arc cutting of steel and copper welding, cutting rivets, removing casting margins and defects, gouging electric tacks and welds at a current of up to 1000 A. Consumables are quite popular, so their scope is wide. Graphite electrodes are used to perform a number of tasks. Graphite rods are suitable for treating metal surfaces before welding and cleaning parts. With the help of graphite electrodes, it is possible to reduce the risk of defects and avoid seam defects. Several main directions in the use of consumables are determined: welding of non-ferrous alloys; elimination of defects when creating a cast alloy; fusing hard alloys onto a metal base.
