2.0MM-5.0MM Submerged ARC Welding Wire in the role of welding
2.0MM-5.0MM Submerged ARC Welding Wire production process is very good, with many years of history, in the welding process has the following aspects of the role:
1. Improve the stability of the arc combustion. No light of the welding electrode is not easy to ignite the arc. Even if the ignition can not be stable burning. In the electrode coating, usually containing potassium, sodium, calcium and other low ionization potential of the material, which can improve the stability of the arc to ensure that the welding process continues.
2, to protect the welding pool. 2.0MM-5.0MM Submerged ARC Welding Wire During the welding process, oxygen, nitrogen and water vapor in the air are immersed in the weld, which can adversely affect the weld. Not only the formation of pores, but also reduce the mechanical properties of the weld, and even lead to cracks. While the electrode coating melted, the resulting large amount of gas enveloped the arc and molten pool, will reduce the melting of metal and air interaction. When the weld is cooled, the molten skin is formed into a slag, covering the surface of the weld, protecting the weld metal and allowing it to cool slowly, reducing the possibility of generating pores.
3, to ensure that the weld deoxidation, 2.0MM-5.0MM Submerged ARC Welding Wire dephosphoric acid impurities. Although the protection of the welding process, but still inevitably a small amount of oxygen into the pool, so that metal and alloying elements oxidation, burning alloying elements, reduce the quality of the weld. Therefore, the need to add in the electrode coating reducing agent (such as manganese, silicon, titanium, aluminum, etc.), so that has entered the molten pool of the oxide reduction.
4, for the weld to add alloying elements. Due to the high temperature of the arc, the alloying elements of the weld metal are burned and burned to reduce the mechanical properties of the weld. Therefore, it is necessary to add appropriate alloying elements to the weld through the coating to compensate for the burning of the alloying elements, 2.0MM-5.0MM Submerged ARC Welding Wire to ensure or improve the mechanical properties of the weld. For some of the alloy steel welding, but also need to penetrate the alloy through the coating to the weld, so that the metal can be welded with the base metal metal components close to the mechanical properties to catch up even more than the base metal.
5, to improve the welding productivity, reduce splash.
2.0MM-5.0MM Submerged ARC Welding Wire manufacturers to introduce you to the core 2.0MM-5.0MM Submerged ARC Welding Wire production, core 2.0MM-5.0MM Submerged ARC Welding Wire manufacturing process control is very strict, because the molten metal from the steel Leather and flux components, pre-manufacturing size and chemical composition are required to check in detail to ensure quality.
As the internal space of the welding consumables is limited, the size of the flux particles becomes more important, the formation of particles similar to the nest together, the flux composition elements are not uniform. Most of the core 2.0MM-5.0MM Submerged ARC Welding Wire by a flat metal sheet length by rolling through the U-shaped section, the granular flux filled in the U-shaped metal tank and then the final seal rolling steps , The flux tightly rolled in the tube 2.0MM-5.0MM submerged arc welded wire into the tube-shaped 2.0MM-5.0MM Submerged ARC Welding Wire and then through a series of pull action to become the last required wire diameter, the pull of the Action can also be filled with the flux evenly fixed in the 2.0MM-5.0MM Submerged ARC Welding Wire. Manufacturing / production process how to not make 2.0MM-5.0MM Submerged ARC Welding Wire due to poor control caused by the formation of part of the wire hollow (no flux) is the core 2.0MM-5.0MM Submerged ARC Welding Wire production quality key. Another wire surface also need smooth smooth and clean, otherwise it will affect the smooth wire and welding current transmission. 2.0MM-5.0MM Submerged ARC Welding Wire wrapped into a package or into a barrel to avoid the intertwined or damaged wire, usually into a roll of silk are coated with a plastic sleeve and placed desiccant to avoid the material damp, encapsulated material and then put Into the carton.
2.0MM-5.0MM Submerged ARC Welding Wire in the daily life of the use is very large, in the recent observation found that 2.0MM-5.0MM Submerged ARC Welding Wire manufacturers on the 2.0MM-5.0MM Submerged ARC Welding Wire more and more , The focus for everyone to introduce the gas-protected 2.0MM-5.0MM Submerged ARC Welding Wire related knowledge.
The gas here refers to carbon dioxide (CO2), the use of the gas production of gas-protected 2.0MM-5.0MM Submerged ARC Welding Wire has a good process performance, and the melting speed, high melting efficiency. Colleagues also have arc stability, welding spatter very small, uniform and beautiful weld characteristics. More suitable for welding low carbon steel and low alloy structure, such as ships, vehicles, bridges, containers, construction machinery, boilers, construction and so on.
The above is 2.0MM-5.0MM Submerged ARC Welding Wire manufacturers finishing on the gas-protected 2.0MM-5.0MM Submerged ARC Welding Wire professional introduction, if you still want to know, please feel free to call the website of the phone, or to the company to study The
