Introduction of ARC Welding

The is most widely used Arc welding welding method. c. Most arc welding is the heat source between the electrode and the work piece. When. To make the joint, you may or may not use filter metal. The electrode used is a melting electrode during the welding process, Which is called melting electrode arc welding, such as manual arc welding, submerged arc welding, gas saving arc welding, tubular electrode arc welding, etc. The electrodes used do not melt carbon bars or tungsten bars during the welding process. They are called non-melting polar arc welding, such as tungsten electrode arc welding, plasma arc welding, etc.

Manual arc welding

The is most one of Manual arc welding widely used welding methods in various arc welding methods. It is electrode and filter metal coated with paint, and is burned between the end of the arc electrode and the surface of the welder. The coating can produce gas to protect the arc on one hand, while the other hand can produce slag to cover the surface of the molten pool to prevent the interaction of the molten metal with the surrounding gas. Creating a more important role of slag In addition to the physical-chemical reaction or the alloying element for the melting of gold, improve the performance of the weld metal. Arc RV welding equipment is simple, lightweight and flexible. It can be used for maintenance and welding of short joints in assembly, especially for hard to reach. Manual arc welding parts. Welding electrodes can be used for most industrial carbon steel, stainless steel, cast iron, copper, aluminum, nickel and alloy.

Frozen arc welding

Submerged arc welding is used as electrode and filter metal in continuous transmission. When welding, a layer of granular flow is covered in the welding area, and the arc is burned under the flow layer, to melt the end of the electrode and form the local parent arc. Under the action of arc heat, the flow slags of the upper part melt and react with the liquid metal. The molten metal spreads slag flowers on the surface of the pool. On the one hand, welding can produce physical and chemical reactions with the matte metal to protect the metal, prevent air pollution and improve the structure and performance of the welding metal. On the other hand, weld metal can be slowly cooled. The existing dam can be used for arc welding. Manufactured with hand arc welding, its biggest advantage is that the weld quality is good and the welding speed is high. Therefore, it is especially suitable for straight seam of large work pieces. And most of them are mechanically welded. Arc welding is widely used in welding of carbon steel, low alloy structural steel and stainless steel. Therefore can slag joint, cooling hydraulic steel, high carbon steel and others. Dam adopts arc welding.

Tungsten gas saved by arc welding

This is a kind of arc welding which does not melt the row gas. It is used to melt metal and make welds with tungsten electrodes and electric arc between work piece. Tungsten is highly demolished during welding, and only electrodes are used. It is also protected by torch or helium gas torch. Jobs. Additional metals can be added as needed. It is sent internationally as tie welding. Tungsten gas shielding arc welding is related to a sheet metal and bottom welding because it controls the heat input well. This method can be used to form almost all metal connections, especially metals such as aluminum and magnesium such as oxygen oxides and ideally titanium and zirconium. The weld quality of this welding method is high, but compared to other electric arc welding, its welding speed is faster.

Plasma arc welding

Plasma arc welding uses a non-melting electrode arc welding. This is to use the arc (call the forward transfer arc) to withstand welding. The electrodes used are usually tungsten. Can be used for Lisa gas produced by plasma arc. Arginine, nitrogen, helium or a mixture of both. Drains are also protected by abnormal gas. Welding can be incorporated into metal or not to fill metal. Plasma arc welding welding arc penetration capacity is strong due to its direct arc and high energy density. Plasma arc welding small hole bearing produced by welding, and for metals in a certain thickness range, It can not open the groove bit joint, and can guarantee access and uniformity of uniformity. Therefore, plasma arc welding has high productivity and high weld quality. However, plasma arc welding equipment (including the nozzle) is more complex, and the parameters of the welding process have more control requirements. Tungsten gas shielding arc welding can be soldered by metal plasma arc welding. In contrast, the use of ultra-thin metal welding under 1 mm is easier with plasma arc welding.

Saved arc welding

To welding electrode gas This welding method is used to weld the arc of gas which is emitted by the welding torch nozzle. Protective gases are commonly used to protect arc welding. These are argon, helium, CO2, or a mixture of these gases. Or helium gas, this is called protective arc welding of melting polar inner gas (known as Mg welding); Gas protection with gas and oxygen gas mixture (O2, CO2), or air with CO2 or CO2 + O2 mixture protection, or saving gas as CO2 or CO2 + O2 mixture, collectively as melting pole Known as the body of gas safe arc welding (referred to in the world as mag welding).The main advantage of welding electrode is that it can be easily soldered in different positions, and it also has high welding speed and high melting rate. The welding electrode is suitable for the largest metals including carbon steel and alloy steel. Suitable for welding stainless steel, aluminum, magnesium, copper, titanium, zirconium. And nickel alloys. This welding meter can also be used method for arc spot welding.

Tube wire arc welding

Tyler electrode arc welding is also used for flame welding between welding wire and workshop, which can be considered as a type of welding electrode. Wire is used immigrant wire, which contains the flow of various components. When welding, pulse protective gas, mainly CO. The welding agent is removed or melted, and slag is used to protect the melt pool, alloy and RSC. In addition to the advantages of welding electrodes, tube welding electrodes have advantages in metallurgy. The use of tube wire arc welding can be applied to the welding of most black metal joints .Bubble wire arc welding is widely used in some modern industrial countries.
