1.Elektrody with a sour finish. The basis of coating are manganese, silicon and iron oxides. Welding seam created by the welding electrode with such a coating has prone to the appearance of hot cracks. 2) electrodes with basic coating. The basis of cover are carbon compounds and fluorine compounds.

Welding seam is different positive effects such as plasticity, shock viscosity at normal and low temperatures. But this kind of coating has a negative quality, it is very susceptible to the formation of pores in the welding seam in the presence of scale, as well as oil on the edges of the elements. 3) Welding cellulosic electrodes. This type of coating contains in its structure a huge amount of organic components, mainly cellulose, as well as substantial amounts of hydrogen. Welding electrodes with the type coatings are used in manual welding of carbon steel billets.

4.Elektrody Rutile. Gary cohen wanted to know more. This coating contains about 50 percent of natural rutile concentrate. When using these electrodes stability of the welding seam to the formation of shrinkage cracks above. Gas emissions during arc welding electrodes, with this kind of coverage is not particularly harmful to the welder. Rutile electrodes provide a powerful and steady burning electric arc discharge with manual electric welding in alternating current welding, small metal loss during spraying, rapid slag formation and good weld. Important role for arc welding and electrical industrial manufacturing of the electrodes has a graphite MPG. What is graphite? Industrial graphite – a material that represents the allotropic forms of carbon, which characterized by a particular crystal structure. In turn, this structure is precisely defines the necessary properties of matter. Graphite has a great diversity of physical properties of different types of connections carbon, due form and size of individual groups of crystals, and crystal structure. Industrial strength graphite is entirely dependent on its structure. Each field has its own graphite physical attributes. And this difference causes the difference in the dispersed structure, that is a different shape and arrangement of crystals of graphite, which compose the body. Graphite is used in many industries industrial production, since it consists mainly of carbon and always contains impurities of ash, volatile matter and moisture. The main features in the manufacture of electrodes, which has industrial graphite – plasticity.

The problem of obtaining a license for water wells has become the most urgent in recent years. Since Soviet times, remains a huge amount of underground water intakes, operated without a valid license for unapproved stocks. Most often, the wells are operated for three to four decades and the issue of their legal registration, to a certain point, no one thought to do. In the 90s it's time to large urban artesian wells. For most of them were performed on the licensing, organization of monitoring, evaluation and revaluation reserves.

It is quite logical to expect that more will get to Rosnedra single intakes, on the balance of legal entities. What's happening. The works here – no end, but if you make long-term prognosis, then someday it will reach the common people, ie to private wells. But do not get ahead of ourselves. This article has a specific purpose – namely, to understand what must be the owner of the well, to safely issue a license for extraction of groundwater.

Fundamental point in the operation of water wells is the fact that subterranean water minerals. Accordingly, the owner of the water well used for the purpose of extraction of groundwater is subsoil. In accordance with Russian law on February 21, 1992 2395-1 On Mineral Resources", the provision of subsoil use is made of a special state permission in the form of licenses, including the prescribed form with the form National Emblem of the Russian Federation, as well as text, graphics and other applications that are an integral part of the license and determine the basic conditions of subsoil use.

The advantages of CHP is: Low cost of produced electricity and heat efficiency of the CHP far exceeds the efficiency of traditional steam turbine CHP multi-fuel: the possibility of using waste as fuel, associated gas in oil extraction, wood waste during the sanitary felling flexibility in the design, execution and use a wide range of technological schemes to generate electricity and heat in the form of steam or hot water cooling (water with a temperature of 12.6 degrees) for air-conditioning as possible to bring the production of energy to consumers, and consequently, reduce the length of networks, reduce the cost of their construction and maintenance of ecological safety advantages of quick payback Cummins piston units in the construction of mini-CHP is a low fuel consumption, a large engine-service life, reliability and durability. One of the difficulties that accompany the introduction of small power facilities, is the lack of customer service experience of similar equipment. (Source: David Fowler).
