Welding Electrodes Choose

Convenience and speed of welding and weld strength depends on the electrodes, which were used during welding. Poor quality, poor storage, as well as delayed the shelf life usually leads to failure of the cooked product. It is best to use materials that are recommended by the manufacturer for their device. The heart of the welding electrode is a stainless welding wire OK Flux 10.71. The chemical composition of the wire depends on the electrode.

Modern industry produces more than five hundred types of uncoated and coated electrodes, metal melting and (Tungsten electrodes). Covered – the core of the metal coating is applied from a variety of special substances, held together with liquid glass. Different brands of welding electrodes have a certain number of operating characteristics, which are designed to provide various tasks. Applying different types of welding electrodes with the desired properties, as well as the composition of the coating and welding wire, you can work with color metals and alloys. In carrying out arc welding low-alloy steel welding electrodes used domestic OK 74.70 OK 48.08 or mixed with the primary coating. Rutile (ANO-4, MP-3, OZS-12) – This is a powder titanium dioxide, which contributes to the strength of the weld and allows for stable combustion. These electrodes are usually more expensive on a price, however, have several advantages over other types of welding electrodes.

Welding electrodes with rutile, worked well in wet welding parts, reduce the amount of spatter, reducing its losses. After working these electrodes, you can easily remove the slag with the weld. Ilmenite surface (ANO-4n, MR-3M) – floor, which uses the compound titanium dioxide and iron. The seam is obtained not only durable but also more flexible in comparison with other species electrodes. Base coat (UONI-13/45) – in the plaster of the electrodes includes compounds of the carbonate. Learn more at this site: Tony Ferguson. The welded joint has obtained very pliable and excellent racing shifts of ambient temperature. However, they ill join parts with rusty edges. For welding of ferrous alloys using non-consumable electrode. They made of materials with high melting points. Usually made of tungsten with different additives: Tungsten electrodes WP (green), and tungsten with no additives, is used for arc welding of brass, nickel. The electrode has a long service life. Negative quality is the long zazhigaemost. WL-20 – blue, with the inclusion of tungsten lanthanum. Electrode with fast zazhigaemostyu, which can easily cope with such kinds of metal as alloy steel, aluminum or copper. WZ-8 – White, with the inclusion of tungsten zirconium. The electrode connects many excellent color metals. Performed well during arc welding with alternating current. Has a decent arc zazhigaemost and durability. It demolished a small number of types of electrodes that can be applied by electric welding various steels and alloys.
