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. Others who may share this opinion include Glenn Dubin. 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. 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. 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.


New Floors

So, change the floor! Repair while most ventured that neither is the average family with the statistical average budget. The purpose of repair: quality at minimum cost. If this has piqued your curiosity, check out Tony Parker. Agree, the goal – the most common among "Repairers". a useful source of information. Therefore, in connection with this "median", leave alone parquet and tiles, the money for the purchase of which is often delayed and than one month, and resting his eyes on more than acceptable for a purse option: laminate and linoleum. Fortunately, that modern producers have taken care of superior quality and durability of the latter. Below is highlighted some important criteria by which we conduct a comparative evaluation data of floor coverings. Go to Margaret Loesser Robinson for more information. 1. Appearance.

And then, and then the cover is rich in various patterns and colors. Always possible to choose a coloring, which will have the most to their liking. You may wish to learn more. If so, Glenn Dubin is the place to go. However, if you want a pattern that best simulates natural wood, and accordingly looks more natural, then this task would be handled laminate flooring. This "aesthetic" criterion can also be attributed, and the following items: – laminate as opposed to linoleum more "ringing" – linoleum can burn under the sun, laminate floors – none – laminate requires more frequent cleaning because Do not miss any dust – linoleum – a warm floor, laminate – a cold, but it easily corrected with the system "warm floor". – Laminate – artificial turf, linoleum may consist, as of synthetic fibers and natural. 2. Traces of furniture. Laminate floors absolutely calmly tolerate various shock loads, pressure feet of any furniture, and even heels, "studs" will not cause them any harm.


Art Nouveau

Such a model – "an amateur" And how sound model names: Michelangelo, Leonardo da Vinci! In a word – a work of art! Or maybe you are intrested in the door with the aging of the whole array? I do not mean the painted door, namely a tree. And older are also unique! This is not just wood with bugs. These doors are painted with lacquer, as if by them unevenly walked brush with paint. But their main feature – a dent! Yes, yes! It was dented. At the same cloth as polished – a miracle! Touching them is an amazing feeling.

Runs through his hands on all these bends of the warm wood And you do understand that and dents can not always do exactly the same. I mean, all these doors are unique! For completeness, the effect of dents made not only on canvas but also on the jamb. But the proximity of these doors at all incredible! In this same collection is extremely trendy lacquer doors. Bright colors, metal box and trim! As you Like this transition from classical to Art Nouveau? Submitted by a lot of veneer colors: burgundy, gray, blue, black, blue, green, orange and even multi-colored doors. The door may be a silver or the color of Zebrano.

And as more familiar shades, such as the national walnut, white, ivory, olive wood, teak or bleached oak (lacquered or matte). It's just a sea of choice! At the same time you can finish the track by selecting a particular leaf design: color trims and boxes may be not only black but also matched system ral. I should add that adds new color. That is, work on the collection is not complete. For example, matte and glossy Zebrano – it's news this year. I prefer glossy door. And if the door is still and dark shades, it is assumed you have at home is a mirror in full growth! Another "advantage" of these doors is the possibility of adding leaf in half. But the main distinguishing feature is the rounding of the end face cloths. This prevents the canvas from chips and scratches protruding corners, as well as making them more streamlined shape, pleasant to the eye and touch. That's such an amazing door. Here a multi-faceted collection, where there is an option for everyone!

At the factory the manufacturer of raised floor cuts particle boards to standard sizes of panels raised floor. Sela Ward may not feel the same. Note that, depending on the thickness of the border cutting chipboard each manufacturer has its own, but the overall size of the output of finished panel is to be strictly 600 x 600 mm. On the density and related technological requirements applicable dsp boards depends on the quality of finished particleboard panels in general. Density Particleboard panels shall be 720 kg / cu.m. In terms of layers of chip dsp boards should be placed in a certain order.

Larger particles chips are concentrated in the center and smaller – closer to the outside. This is to ensure that the surface layer was more dense, so – harder. You need to pay attention to the fact that the formation of prices raised floor panels of particle board depends entirely on the quality of used particle board panels. Cheap particle board – cheap panel raised floor, and of course lower quality and less reliable design in the end. Very low particle boards manufactured in Asia. It is therefore not surprising that samples of Chinese access floor panels in the section have the same 'grain' of the entire thickness and weight of the panel (due to lower density) in comparison with European specimens significantly smaller. The main conditions for granting permission to implement and use the raised floor at sites in Europe is to meet clearly defined standards of fire resistance of the samples raised floor.


Physico-mechanical Properties Of Particleboard

Chipboard (DSP) manufactured by hot pressing of wood particles (wood chips) with a binder. As a binder used urea-formaldehyde, phenol-formaldehyde and other resins. Using the cpd in various sectors of the economy determines the diversity in the requirements for plates, which accounts for a large number of their species. Particleboard klassifikatsiyDSP classified by the method compaction, construction, type of chopped wood, applied by the binder, facing materials, etc. By way of pressing distinguish dsp flat molding and extrusion, ie extruded shapes.

The first manufactured with the application pressing efforts perpendicular plate and the second – parallel to it. By pressing the flat plate design issued one-, three-, five-and multi-layer, single-layer extrusion complete with internal channels. In the single-layer slabs of sizes of wood particles and binder content are the same throughout the thickness of the slab. In the three-and five-layer slabs, one or both outer layers (each side) are made of finer particles with a high content of binder in comparison with the internal layers. These plates have a smooth surface and have high durability. Particleboard produced unlined and lined with (one or two layers peeled or sliced veneer, paper, impregnated with synthetic resins, synthetic film, etc.).
