No matter how big they are, dogs seem to love touching noses with people and other animals. In fact, nose touching is a form of social interaction for dogs, much like shaking hands and hugging humans. But dogs don’t rub their noses with every person or animal. They choose who to rub their noses with. If they don’t like you or don’t know you at all, they won’t touch your nose. However, adult dogs will touch the nose of almost every puppy. They will not only touch the puppy’s nose, but also smell the puppy.

- First of all, the protective layer of zinc-iron alloy can prevent the steel wire from being corroded by oxidation. The zinc metal reacts with water and oxygen to form a dense zinc oxide layer, which forms a physical barrier to prevent oxygen and water from entering the inside of the steel wire, reducing the chance of corrosion. Compared with ordinary steel wire, hot-dip galvanized wire is more resistant to corrosion in humid, high humidity or corrosive environments such as acid and alkali, so it is more durable.

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.

Titanium alloy with low carbon content is obtained because the carbon content remains the original concentration. The hardness of titanium alloy is mainly related to its carbon content. Therefore, after carburizing and subsequent heat treatment, the workpiece can obtain the performance of hard and tough inside. Galvanized wire varieties are mainly classified into three categories: electric galvanized wire, hot galvanized wire and galvanized wire. Among them, the classification of galvanized wire is divided into large roll galvanized wire, medium roll galvanized wire, small roll galvanized wire, galvanized shaft wire, truncated galvanized wire and other main production varieties.
