Wire mesh welding after galvanized is through the end of the welding and then the cold company to make wire mesh wire mesh steel mesh construction mesh floor heating mesh galvanized or hot galvanized. After the first galvanized welding is to change the wire mesh, after the end of welding can see the welding spot; The two processes are different prices are also very different, the cost of the first plating after welding is low, the appearance is smooth, and the cost of the first welding after plating is higher, not easy to rust.
The tensile strength of cold drawn spring steel wire is slightly higher than that of oil tempered steel wire. The large specification of cold drawn steel wire elastic force is too large, winding the spring is very difficult, so the cold drawn spring steel wire application specification is generally less than 8.0mm, oil quenching tempered steel wire application specification is generally less than 13.0mm. In fact, the diameter of 13.0mm spring is used to light tension spring steel wire, cold drawing wound made into shape and then quenched and tempered. Steel wire with diameter above 15.0mm is mostly made by heating winding process.
Some large roll galvanized wire products in order to meet different industrial needs, will be further processed on the surface, such as the anti-corrosion layer, galvanized, iron plating, aluminum alloy plating, or in the galvanized wire appearance above the copper plating, brass plating, etc., to strengthen the steel wire and colloidal years and capabilities. Generally, galvanized wire products should be well plated and drawn when they are produced, and the sequence of the two processes should be decided according to the production or industrial needs.
Field fence line net is a streamlined, streamlined, beautiful, tacky, fashionable European elegance; The diversity of color selection, a variety of standard color card color choice, can meet different varieties, different needs. The field fence line network can be separated with a variety of methods, and according to the customer’s request.
Electrode application range is wide, can realize a variety of materials, a variety of profiles and a variety of joint forms of welding. (1) Welding between low carbon steel, low alloy steel, medium carbon steel, alloy steel and other metal materials or dissimilar metal materials can be achieved. The weld has good comprehensive mechanical properties, and the tensile strength can reach more than 400MPa. ⑵ Can realize the welding of large plate, steel frame, plate – tube, rod – rod, tube – tube and other profiles. ⑶, can realize docking, Angle, lap, T joint and other joint forms of welding. ⑷ mainly suitable for flat welding.(5) it can surfacing the parts of wear failure, so as to obtain the surface surfacing layer with melting depth, smooth surface and excellent performance. ⑹ It can be realized that no bevel 1 ~ 6mm thick metal sheet single-side welding double-side molding.
Galvanized wire can be seen as iron wrapped in carbon. When extinguished, the surface layer is more shallow than carbon can contact with oxygen, produce carbon dioxide gas, and radiate the iron wrapped in it. The more carbon galvanized wire contains, the more obvious the phenomenon of spark. The carbon wrapped in iron acts as if it were an explosive in a charge bag, occasionally blowing the iron apart. Sodium and magnesium contain few flammable impurities, and when extinguished, they just glow.
Wire mesh is the iron screen with high corrosion resistance, the same is also one of the iron net class of widely used net class, its efficient corrosion resistance function in breeding industry, construction industry and other aspects are much liked. Its smooth and neat net surface, not only increased their aesthetic feeling, but also can play a certain decoration effect.
The application of electric welding net is more widely, at present it has replaced the use of other parts of the wire mesh, the cost of electric welding net is lower, the production speed is very fast, so it is very popular. Welding net galvanized before the need for processing is recrystallization annealing, because the welding net must maintain a no oxide and no other impurities of pure iron active surface, if you can not keep its surface clean will lead to a bad galvanizing effect, galvanized layer and iron material is not closely combined, so this step is necessary.
