Welding Electrodes

Electric arc welding has been known to mankind for a long time and was nearing perfection. At the moment, welding can be performed under any climatic conditions, different materials. To carry out any tasks there exist different welding equipment. Very important component of welding equipment are welding electrodes. High-quality alloy and durability of sodium product depend on properly selected electrodes.

Also pay attention to quality, storage and shelf life of electrodes. Failure to observe safety precautions may result in inoperability cooked products. Various types of electrodes due to various technical indicators, which are responsible for performing any tasks. The electrodes consist of a metal rod or wire, that conduct electricity. The composition of the wire depend characteristics of the electrodes. Different electrodes coated and uncoated.

Coated electrodes. To improve the quality of the alloy wire coated with a special compound. Distinguish between certain types of coverage, such as sour, basic, rutile, cellulosic and blended, ionizing and protective. Also distinguish between melting and non-consumable. By the consumable electrode is copper and aluminum. For tig – Tungsten, charcoal. Often the use of carbon electrodes used in the case when important appearance of welding products. Tungsten electrodes are considered to be one of the best classes and types of weld metals. Wolfram maintains its density even at very high temperatures. The weld metal comes from the additional filler materials. Manufacture of electrodes requires a very different process operations as processing materials, and electrodes in general. During welding, the use of tungsten is only hundredth of a gram per 1 weld, despite this, the tungsten electrodes are very stable. Some brands of tungsten electrodes are used during arc welding in inert gas. Quite often the tungsten electrodes used for welding nonferrous metals, and welding metals of different chemical composition. In order to increase strength, improve Indicators seam for universal works in tungsten added some chemicals. Each electrode has its own unique markings. Types of tungsten electrodes: wp, WC-20, WL-15, WL-20, WT-20, WZ-8. And also distinguish between domestic brands electrodes: va, il, superfluorescent fiber and international brands of electrodes: WT-1920, WL-20, WC-20, WZ8, wp, WY-20.
