The company Evek GmbH is a supplier of electrodes Evi-1, Evi-2, Evi-3 and other tungsten products. Order and buy the electrodes Evi-1, Evi-2, Evi-3 on the website of the company. Now consider the products - in general, welding electrodes are an indispensable component for welding, especially they are widely used for arc welding. The task of the electrode is to supply electric current to the welding area to produce an arc.
Properties and purpose of tungsten electrodes
The price of Evi-1, Evi-2, Evi-3 electrodes is largely based on their properties and characteristics. Like other tungsten elements, they are non-consumable, so they are used in welding simultaneously with filler wires. Buy Evi-1, Evi-2, Evi-3 electrodes are recommended for welding with non-ferrous metals, their alloys and high-alloy steels. The supplier of electrodes Evi-1, Evi-2, Evi-3 shows that the product provides the formation of high-strength welds, while the elements to be welded can have a different chemical composition.
Buy Evi-1, Evi-2, Evi-3 electrodes and other tungsten elements are recommended for welding in an argon environment, which has a positive effect on the welding process and weld quality.
Product Features
The main feature of which the supplier of Evi-1, Evi-2, Evi-3 electrodes warns is poor arc ignition. It occurs in three stages. In these grades, yttrium is added, which ensures the use of products in a variety of current environments. In addition, the considered elements are excellent for working with copper, titanium alloys, stainless low-alloy steels, which to some extent affects the price of EVI-1, EVI-2, EVI-3 electrodes. Tungsten electrodes with yttrium additive are the most resistant among other tungsten elements used for welding. The diameter of the products is from 2 to 10 mm, its surface is polished and without defects.
Purchasing and Cost
The price of the electrodes Evi-1, Evi-2, Evi-3 if necessary to purchase should be clarified with the managers of the company, bearing in mind that regular customers and wholesale buyers can count on the possibility of flexible discounts. The company has a wide range of products in stock, which guarantees timely deliveries.
