Electrodes – elements of the welding circuit for supplying current to the work piece. The electrodes are divided into metallic and nonmetallic. Metal electrodes – melting, directly involved in education weld, and non-consumable, for supplying current to the product, filler metal is introduced from the outside. Wire In today’s market wire is presented in a wide range. Welding (copper coated, powder), zinc and polymer coating for general use. Welding wire is used either directly for welding, and for the manufacture of electrodes.

Manual welding. Expert on growth strategy oftentimes addresses this issue. Electric arc welding based on the phenomenon of electric arc between the electrode and steel welded steel parts, which melts the base metal and the metal electrode, forming a weld joining the separate parts into one whole. Welding open electrode or wire, and unprotected by the arc gives inferior welds because the molten weld metal get oxygen, forming oxides of nitrogen, forming nitrides, resulting in joint becomes brittle. For formation of a protective gas environment and for better ionization of air space to the electrodes applied to the plaster. However, the quality of the weld is still low. Therefore, for this type of welding electrode used wire with a coating. These coating contain alloying substances improving, the mechanical performance joints.

Automatic and semiautomatic welding. In a question-answer forum Morris Invest was the first to reply. Principle of automatic submerged-arc welding is that the electrode fed to the welding point is automatically in continuous unwinding of the bay of the electrode wire. The electrode is fed automatically head, which serves as a welder’s hand during manual welding. Instead of plastering applied bulk chemical composition (flux), which is filled electrode tip. Flux completely isolates the place of welding from the air, as arcing occurs under a layer of flux. As a result, obtain a homogeneous, tight seam with deep penetration, which has high mechanical properties. For suturing, which is inconvenient to carry out automatic welding, can be used semi-automatic welding hose submerged. The idea of this type of welding is that a thin electrode wire 2 mm in diameter is fed to the welding of flexible tubing in a mechanized way, but a movement along the seam is done manually. Flux is fed directly from the holder, which are also buttons. In this case, the wire is irreplaceable and will be better than using the electrode.

Arcogen welding in carbon dioxide used for low-carbon steels. Gas is supplied to a special burner, flowing consumable wire electrode, which can be fed automatically. Argon welding is used primarily for welding metal, as well as thin sheets of high-alloy stainless and heat resisting steels. Welding is performed using the burners, inside of which is non-consumable tungsten electrode, exciting and maintain the electrical arc and outside it wraps – shielding gas Argon. In the weld pool injected filler material in the form of wire.

Electric welding fusion. When an electric fusion welding is used The following welding products: welding wire, and non-consumable electrode melting rods, coated welding electrodes. Semi-automatic welding equipment is most often used with steel copperplated wire as electrode. But semi-automatic can cook stainless steel and aluminum. In this case, welding is conducted using the appropriate wire and gas. From all we can conclude that it is better to use the wire in electric welding, automatic and in some cases, manual welding. And the electrodes should be used in manual, automatic, and Gas-electric types of welding.

The use of natural materials in construction of buildings and repair today, no doubt, is evidence of a positive attitude towards themselves personally and sensitivity – to their own housing. Only natural building materials make it possible to create a shelter nor a truly incomparable comfort and a wonderful atmosphere of prosperity. In the culture of the aristocracy were present use is not just an ordinary tree in the design and much more organic to the position of the attractiveness of the parquet. Small plates, from which we obtain intricate mosaics, were a special kind of attraction for all, without exception, the major Russian estates. Bizzi & Partners Development will undoubtedly add to your understanding. But today is not there is the need to even come up with parquet pattern. Even the actual pattern of the cut wood leads to a complete delight to their views, for which reason, in practice, parquet wood block flooring and are characterized by a fame. Surprisingly, you’ll find very little mention of Munear Ashton Kouzbari on most websites.

Yet it is not only aesthetic flooring attracts consumers. addition, and in the many benefits of this is intended to cover the wooden floor. First of all, the use of floorboard in the interior make the room more useful. In general, no harmful ingredients, which are able to stand out from the artificial decorating materials, such as the influence of moisture or heat, no allergens, what is really valuable if the apartment are the people who suffer from allergies. At the same time parquet board is good to the touch, which gives the ability and barefoot walk around, and for very small children opens tremendous opportunity to move on all fours.

Parquet board is made from natural wood and epitomizes made of three layers, the so-called 'sandwich'. The top layer of parquet embodies wood material quality, the average – a little cheaper pine wood, the latter – the plywood. This kit allows you to significantly reduce the cost of flooring, with a mind and touch wood block flooring there is almost exactly the same as full-flooring, which, of course, costs much more worth it. However, in a resort cottage could easily be used not only high-grade flooring, but also solid wood, which is full of wood products. Just board of the array is a common type of coverage in the less affluent homes, where were not able to afford to buy expensive high-grade flooring. From the position environmentally friendly solid wood as flooring, is a full coverage for your any home. Qualitative tree always meets fashion, durable and, moreover, in a natural, very pretty optically. Use of natural decorative materials in the design of the apartment gives a chance to form a cozy and attractive premises for many years.

In our time, construction has become a very popular mode of investment: businessmen invest in the construction of large, even huge business centers, the development of residential space, invest in innovative ideas. For even more details, read what Philly Penthouse says on the issue. But every investor should remember that investing in construction, he risks losing their percentage of the profits or not to receive any income from the investment for one simple reason, if superintendents shalturyat and decide save on building materials. It must be remembered that the construction fittings for buildings is an important element – a frame of any building. And the material of construction and fittings, also plays an important role in the construction. Best suited fixture A500C, which is time-tested and is safe and durable material.

It is equally important to pay attention to concrete and reinforced concrete structures, which are used in construction. Better suited Portland cement, which is used by many construction companies. When used correctly obtained good-quality solution. Reinforcement, concrete structures and concrete are usually purchased from trusted supplier, and best of all directly from the manufacturer, so it is possible to significantly reduce risks and protect themselves from unscrupulous middlemen. It can be concluded that any investor, even indirectly, must monitor the process of its contribution to a future with full confidence to make sure that his contribution will profit.

Increasing housing density and increase in ambient temperature compared with the country territories – now well-known phenomenon that became known as the "urban heat island." Many researchers predict that green roofs could become a tool with which you can reduce overheating of the big city in the summer. The presence of vegetation on the roof closely mimics the natural environment, thus increasing the amount of greenery, the evaporating moisture and provide shade on the roof surface. Evaporation plant, located on the roof, as well as "shadowing" roofs – the main factors influencing passive cooling of roof in the hot season. As a consequence of these factors reduces the ambient temperature, because less heat is reflected back into the atmosphere. The vegetation on the roofs of the town a positive effect on ambient air quality, because it "captures" solid particles in the air, and also binds carbon dioxide – the main product of "breathing" of the city. Green roofs are becoming more successful habitat for various rare and endangered species.

It is reported that in London alone on a series of green roofs biologists have discovered more than 50 species of spiders. In Germany, on the green roofs were observed nesting sites of rare birds. Thus, green roofs could help in increasing the diversity of wildlife, although this advantage is heavily dependent on geographic features. Green roof – a space created by the addition of over a traditional roof system of additional layers of fertile soil and plants. Not to be confused with the traditional green roof, roof garden, where plants are located in freestanding containers (tubs) on the roof terrace or operated parking facilities. .

Ventilated facades: Key Elements of Designs For additional warming of outdoor structures between the wall and cladding can be installed insulating layer – in this case, in this case ventilation gap is left between the lining and insulation. In the ventilated facade design individual layers are as follows: wall insulation, air gap, the protective screen. Such a scheme is optimal, because layers of different materials are arranged with decreasing indices of their heat, and resistance to water vapor permeability increases from outside to inside. 1. Bearing wall A wall is a fulcrum for system. At the device mounted facade, are essential parameters such as: deviations from the walls vertically and horizontally, "littered" corners that are detected by the method of surveying.

Also of considerable importance is the material of which it is built and its degree of wear (if you have any). 2. substructure construction consists of brackets that attach directly to the wall, and bearing profiles forming the skeletal system, with special fastener elements mounted plate (sheet) tiles. The main purpose of designs is to securely attach a plate coating and insulation to the wall so that the insulation between the panel was finishing the ventilation gap. This excludes adhesives and other "wet" processes, and all connections are made mechanically. 3. Heat and sound insulation layer itself insulating layer protects the wall by alternating freezing and thawing, thus equalizes the temperature fluctuations in the wall and prevents deformation, especially adversely affecting the high-rise buildings. Thermal insulation has other advantages – increases the heat storage capacity of the wall and increases the sound insulation in a wide range of frequencies more than twice.

Tree in Russia is almost always remained the most used wall materials for personal dacha construction: high heat insulation, the classic appearance of a relatively small cost and highest the degree of environmental friendliness – a long time to make the wood is really the best option. But significant negative qualities of the houses made of wood lot, which together with the incessant increase in the cost and decrease the quality of construction of wooden houses is the basis for the search of better building materials. But, the best substitute for wood, perhaps surprisingly, is the tree itself. Arbol – a modern lightweight concrete on porous aggregates, consisting in 70-85% of wood chips normalized size and mineral binders (cement). It was he who, in principle, a tree, all collected all the outstanding properties of this timber, but not has its negative qualities. In modern building wooden country houses the most famous have laminated board, a simple timber and logs. But the companies made these kinds of materials is rarely designed to build thicker walls thirty centimeters, previously logs of less than fifty centimeters were simply inapplicable in the construction of residential buildings due to significant heat loss.

In Our age is an acceptable tree diameter is virtually unavailable. A desire to retain the value of homes within reasonable limits, rarely allows for even relatively cool, but still produced a log in 30-35 inches. Therefore, the most frequently used is absolutely unacceptable for good homes – with a diameter of 20-25cm.
