The welding process of galvanized steel wire mesh because of low carbon steel carbon content is low, manganese and silicon content is low, will not occur severe hardening or quenching structure due to welding. The low carbon steel joints have excellent plasticity and impact toughness after welding. In the welding process, it is generally not necessary to preheat, interlayer temperature control, post-heating control and heat treatment to improve the welding structure.
There is no adhesion test of powder spraying or fluorocarbon spraying on packaged galvanized wire, but there are two points for reference: first, in sealed or air-free environment, non-metallic volatiles can corrode zinc coating; Second, zinc at higher than 230 degrees (c) will cause the matrix metal brittle. And powder spraying and fluorocarbon spraying are to be baked at a higher temperature and in a sealed environment, causing rapid corrosion of zinc, resulting in loose corrosion film resulting in coating adhesion decline, and even lead to (matrix) steel wire brittle situation may exist.
Hot dip galvanizing is dipped in zinc liquid melted by heating, with fast production speed and thick but uneven coating. The market allows a low thickness of 45 microns and a high of more than 300 microns. The color is dark, the consumption of zinc metal is much, the formation of infiltration layer with the matrix metal, the corrosion resistance is good, and the outdoor environment of hot dip galvanized can be maintained for decades. Application range of hot dip galvanizing: because the coating is thicker, hot dip galvanizing has better protective performance than electric galvanizing, so it is an important protective coating for iron and steel parts in harsh working environment. Hot-dip galvanized products are widely used in chemical equipment, petroleum processing, Marine exploration, metal structure, power transmission, shipbuilding and other industries, in the field of agriculture such as sprinkler irrigation, greenhouse and construction industry such as water and gas transmission, wire casing, scaffolding, Bridges, highway guardrail and other aspects, has been widely used.
Post time: 07-03-23- In order to ensure the electrical conductivity of steel wire, manufacturers need to follow a number of standards and regulations. For example, in the galvanizing treatment of steel wire, the international standard ISO 1461 should be followed to ensure uniform zinc layer thickness and surface gloss. In wire drawing processing, excessive stretching should be avoided so as not to deform the wire or lose its mechanical properties.
Moderate rates of foam formation may be harmless. The presence of small, homogeneous particles of large denier in the tank can stabilize the foam layer, but the accumulation of excessive solid particles can cause an explosion.
The large roll of galvanized wire is like the literal meaning, is wrapped in a layer of zinc on the surface of low carbon steel wire material, beautify the appearance at the same time, but also improve the corrosion resistance of galvanized wire. Zinc dissolves easily in acids and also in bases, so it is called a bi-soluble metal. Zinc changes little in dry air. In moist air, a dense basic zinc carbonate film forms on the surface of zinc.

The reels should be placed lightly, stacked firmly and neatly, not more than 5 reels. Direct contact with acid and alkali must be prohibited. When the acid fog exceeds the specified target of the state, measures should be taken to control it in time, otherwise production is not allowed.
The external environment has a great influence on the storage of cold drawn wire. Especially during the rainy season, special attention should be paid to the air humidity of workshops and warehouses. It is recommended to use moisture test paper with a value between 8 and 10. If the PH value is high, attention should be paid to the corrosion of the internal cold drawing wire. Cold drawing wire in normal environment storage for two years no problem, cold drawing wire will not be corroded. However, it is necessary to place the coil gently during the handling process to avoid the winding position leading to the cable is not smooth.

Post time: 27-10-22Stainless steel barbed rope in the way of corrosion is not very, because the surface is not treated but rely on its own raw materials for corrosion resistance, so there will be no chemical reaction. After a long time of use, it will not rust like the corrosion layer on the surface of hot dip galvanized barbed rope, because the internal material of stainless steel barbed rope is the same as the material on the surface. The most obvious difference in a short time is the cross section of this piece, hot dip galvanized barbed wire because of surface anticorrosion treatment, so there will be rust in the cross section of this piece, and stainless steel barbed wire because the internal raw materials and surface raw materials are consistent, so there is no such situation.
Because of the corrosion resistance of zinc layer, can be applied to all kinds of environment, it is also very convenient to use, has been a more popular hardware products. Galvanized iron wire should pay special attention to the acyl wash, to slowly into the container, to prevent acid sputtering on the body, at the same time prohibit the water into, so it is easy to let the acid out, to learn to handle lightly, stacking should also be firm and neat. It can be widely used in construction, handicrafts and other daily civilian applications.
Because the coating obtained is thicker, hot-dip galvanizing has better protective performance than electric galvanizing, so it is an important protective coating for steel parts used in harsh working environment. Hot-dip galvanized products are widely used in chemical equipment, petroleum processing, Marine exploration, metal structure, electric power transmission, shipbuilding and other industries, in the agricultural field such as pesticide irrigation, greenhouse and construction industry such as water and gas transmission, wire casing, scaffolding, Bridges, highway guardrail and other aspects, has been widely used.

The welding core is the metal core of the electrode. In order to ensure the quality of the weld, there are strict regulations on the content of various metal elements in the weld core. In particular, there are strict restrictions on harmful impurities (such as sulfur and phosphorus), and the quality of the weld core metal should be better than that of the base metal. Arc welding cannot be carried out on a smooth rod without a coating. This is because the arc stability is very poor, splashing is very large, and the weld is not well formed. After long-term practice, it is gradually found that the performance of the electrode is greatly improved by coating the welding core with some mineral raw materials (i.e. electrode coating). (1) Ensure stable arc combustion, so that the welding process is normal. (2) Using the gas produced after the drug skin reaction, protect the arc and the molten pool, prevent the harmful gases in the air (such as nitrogen, oxygen, etc.) from invading the molten pool, such as these gases will cause cracks and pores in the welding material, so that the welding can not achieve the ideal effect. (3) After the drug skin is melted, slag is formed, which covers the weld surface to protect the weld metal, make the weld metal slowly cool, help the gas escape, prevent the generation of pores, and improve the structure and performance of the weld. (4) After melting, various metallurgical reactions will be carried out, such as deoxygenation, sulfur removal, phosphorus removal, etc., so as to improve weld quality and reduce alloying element burning loss.
Stainless steel blade barbed wire production process is similar to galvanized blade barbed wire production process, usually according to the mold to determine the size of the blade.

The formation process of hot dip galvanized layer is the process of forming iron-zinc alloy between the iron matrix and the outside pure zinc layer. The surface of the workpiece forms the iron-zinc alloy layer during the hot dip plating, so that the iron and pure zinc layer is well combined. The process of large roll galvanized wire can be simply described as: when the iron workpiece is immersed in the molten zinc solution, the first zinc and α-iron (body-centered) solid melt is formed on the interface. This is a crystal formed by the matrix metal iron dissolved with zinc atoms in the solid state. The two metal atoms are fused with each other, and the gravitational attraction between the atoms is relatively small.
