What is the effect of the coating on the welding rod?The coating on the welding rod mainly had the following functions:
1. It was to ensure that the deposited metal had a certain chemical composition and performance, and it was made into a coating by mixing the powders such as an oxide-based alloy, a carbonate-based alloy, a silicate-based alloy, an organic compound, a fluoride-based alloy, and other chemical powders according to a certain proportion to meet the needs of welding.
2. In the process of welding, molten slag with suitable physical and chemical properties such as melting point, density, and basicity was formed to ensure the stable combustion of the electric arc and the easy transition of the molten metal. An atmosphere was created around the electric arc area and the molten pool to protect the welding area and obtain good formation and performance of the welding line.
3. By adding deoxidiser, permeating alloy elements or a certain amount of iron powder into the coating, it can meet the requirements of the performance of the welding metal or improve the melting efficiency.
4. The arc-stabilizing agent in the coating can make it easy for the welding rod to start the arc and maintain the stable combustion of the electric arc during the welding process; the slag-forming agent can form molten slag to protect the welding droplets and the molten pool metal and improve the shape of the welding line; the deoxidiser can reduce the oxygen content in the welding line metal and improve the performance of the welding line metal; the gas-generating agent can decompose gas to form a protective atmosphere to protect the electric arc and the molten pool metal and prevent the invasion of oxygen and nitrogen in the surrounding air; Alloying agent is used to compensate for the loss of alloy elements in the process of welding and to transfer alloy elements into the welding line to ensure the chemical composition and performance of the welding line metal; plasticizer can improve the elasticity, elasticity and mobility of the coating during the process of pressing and coating of the welding rod, and improve the quality of pressing and coating of the welding rod; Binder can firmly bond the coating material to the core of the welding rod, and make the coating of the welding rod have a certain strength after drying.
5. isolate the air to prevent the nitrogen, oxygen and other gases in the air that are harmful to the smelting reaction of the welding pool from entering the pool. The molten slag formed after the melting of the welding rod covers the surface of the welding line to protect the welding line that has not been completely cooled. It reduces the cooling speed of the welding line, which is beneficial to the escape of gas, prevents the formation of pores, and improves the structure and performance of the welding line.
6. It participated in the complex smelting reaction, permeating the required alloy elements into the metal of the welding line, and played the role of controlling the chemical composition of the welding line to obtain the required performance of the metal of the welding line. For example, adding Si, Mn and other alloy elements in the coating could remove the harmful gases and impurities such as deoxidization, desulphurization, dephosphorous, etc., and improve the quality and performance of the welding line.

Internet celebrity nano coating agentThe situation of the nano-coating agent was more complicated and could not be simply classified as a scam, but there were some cases where some merchants exaggerated their publicity.
In the field of nano-coating solution for mobile phones, there were merchants who deceived consumers. The nano-coating liquid was a nano-coating. Its real purpose was to improve the feel of the phone screen and prevent fingerprints from being difficult to erase. The effects of the phone screen being intact after being smashed by a hammer, knife, or walnut had nothing to do with the coating liquid itself. Because the phone screen itself had a nano-coating, it was unnecessary to buy the nano-coating liquid.
As for the nano-coating agent for cars, some products claimed to have dust-proof, anti-pollution, oleophobicity and other effects. It could be coated with one spray and one rub. The operation was simple and the effect was good, but there were also opinions that the nano-coating solution for cars was IQ tax.
There was also an electronic protective nano-coating agent, which could be used to protect electronic products and enhance their functions. For example, by soaking, drying, and other simple operations, it could form an ultra-thin dense transparent coating on precision electronic components. It had waterproof, high and low temperature resistance, salt fog resistance, and other properties. The nano-anti-sticking coating of the medical scissors was food grade and had passed the FDA certification. It had the effects of anti-sticking various liquids, non-sticky, and easy to clean. The nano-coating agent for LED small-pitch display screens can improve the ink color and prevent moisture erosion.
Therefore, in the face of nano-coating agents, consumers should treat them rationally and not blindly believe the exaggerated function advertisements of merchants.
