The coating on the surface of the welding core is called the coating. The coating of electrode plays a very important role in the welding process. If the photoelectrode without drug skin is used for welding, in the welding process, oxygen and nitrogen in the air will invade a large number of molten metal, metal iron and beneficial elements such as carbon, silicon, manganese oxidation and nitriding to form various oxides and nitrides, and residual in the weld, resulting in slag inclusion or cracks in the weld. The gas in the weld pool may produce a large number of pores in the weld. These factors can greatly reduce the mechanical properties of the weld and make it brittle.

wire screen panelsDuring this process, each time the wire is pulled over, the surface hardens due to the high friction temperature. So basically every time you pull it you have to annealing it in the furnace. On the one hand, it is to reduce the surface hardness. On the other hand, during the process of wire pulling, only the surface is deformed, and the center is unchanged. So there’s a lot of stress inside. Therefore, it is necessary to rely on annealing to eliminate the internal stress, so that the wire becomes soft again to eliminate the stress before being drawn again.

Post time: 15-11-22- In the production of its own, to avoid injury, wearing the corresponding work clothes is very necessary, so that not only can avoid the occurrence of accidents, but also can better realize the production and processing of products. The application of black iron wire in the process is mainly through the hot metal billet rolled into a six-and-a-half-millimeter wire, and then put it into the drawing device to draw into different diameter of the wire, gradually reduce the aperture of the drawing disk, cooling and annealing, coating and other processes to make a variety of different specifications of the wire.
- Another way is to have special equipment for measuring, which is expensive and impossible for ordinary users to buy. The last method is that there is a hierarchy gap in the light sense of the barbed rope, the general zinc barbed rope is more bright and the high zinc barbed rope is slightly darker, so customers do not think that the more beautiful the appearance of the product is good quality.
The main reason for the high price of stainless steel barbed wire is that the raw material used in the barbed wire is more expensive, because the nickel in it makes it corrosion resistant and ductile. Stainless STEEL BARBED ROPE IS a new type of protective products, precisely because of its corrosion resistance in coastal or often acid rain landing site is widely used, the service life of up to 15 years.

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.
