The main part of the Butt Welding Machine is a step-down transformer, the secondary coil is welded at both ends of the workpiece and the electrode, the work of igniting the arc, the arc in the high temperature welding electrode welded to the gap in the workpiece. As the welding transformer core has its own characteristics, it has a sharp drop in the characteristics of the voltage, that is, after the electrode ignition voltage drop; in the electrode was shortened bonding, the voltage is a sharp decline. Next Xiaobian to introduce the principle of Butt Welding Machine and the advantages of welding machine.
Principle of butt welding
The use of the welding machine is actually when the workpiece contacts the resistance will produce heat, so as to achieve the purpose of heating the workpiece, making the metal surface melting, and the weld is the workpiece counterparts solid phase metal plastic degeneration under the conditions of the formation of a common Grain, weld organization, the composition close to the base metal, so it is easier to get strong and other plastic welded joints. In the flash process, with the discharge of air, reduce the metal oxidation of the self-protection function, making the weld inclusions, not penetration and other defects less.
The advantages of Butt Welding Machine
1, the welding efficiency is high.As the workpiece is pressed with the times the force cylinder, the reaction speed was significantly faster than the hydraulic cylinder.
2, automatic centering function to ensure that the two ends of the pipe before the end of the two ends of the same and the same, so as to ensure the same amount of burning at both ends.
The use of the Butt Welding Machine between the reinforcement and the reinforcement is the largest, can be seamless welding or according to customer needs a variety of welding methods. It is widely used in the manufacturing industry such as wheel rim, tool, tool, wire, wire net, window frame and so on. It has the advantages of high welding efficiency and high weld strength. The ability to weld also varies with varying degrees.
The welding machine is used to crush the two ends of the butt welding parts at both ends of the electrode. After the power is applied, the two ends are pushed forward by the forging cylinder, and the current density of the port is close , The instantaneous liquefaction to form a metal beam and blasting metal splash, that is flash; with the port gradually close, then the point gradually increased, and finally the entire end face are formed numerous liquid metal beams, and continue to blasting, so that the end of the heated to Plastic and liquid critical point after the moment on both ends of the large pressure forging and pressure for some time,Butt Welding Machine the two ends of the welding together to form a solid connector. The welding machine is mainly used for the docking of the end face of the part. It is generally required to have the same end face shape and cross section. It can be used for sheet metal, round bar, square bar, pipe fittings, profile material, including ordinary carbon steel, stainless steel, aluminum, brass, Copper and dissimilar metal docking, docking area of 10000mm2.
The welding machine according to the flash kinetic energy structure is divided into different hand-pull type, gas-liquid mixed type, servo motor type, hydraulic type.
The welding machine is also called resistance welding machine, mainly for high-speed multi-operation, it uses resistance welding method, high power efficiency, good welding effect, can be set of multiple parameters of memory settings, the reaction speed, Small and thus reduce the welding defect rate to a minimum, the equipment is welding wire and cable, bicycle basket, enameled wire, wire wire products, suitcase frame and flat wire the best products.
Structure and features:
Welding transformer using vertical one-way shell body, high welding efficiency, loss of small.
According to different welding objects to replace the use of different welding mold more simple.
The internal voltage of the device is changed from the 380V voltage to 36V, and the safety performance is good.
Applicable to carbon steel, stainless steel, aluminum alloy, copper alloy and other metal materials welding.
The use of the Butt Welding Machine between the reinforcement and the reinforcement is the largest, can be seamless welding or according to customer needs a variety of welding methods. Applicable to wire products, hardware lighting, kitchen utensils, cars, small appliances, hardware, etc. occasions will have the credit of the Butt Welding Machine. The ability to weld also varies with varying degrees.
