fixed large flash butt rail & turnout welding machine with high DC power supply GHDG-800 fixed large flash butt rail & turnout welding machine with high DC power supply, is used in fixed plant to weld short rails to rails of 500 meters and more, or to weld turnouts to rails (Such as high-manganese steel frogs), or weld large alloy parts. This type of welding machine can weld any type of rails and frogs, accurately align the rails or frogs, effectively prevent the rail from slipping during the upset forging, immediately trim after upsetting, and the power supply performance is stable and uniform. This welding machine can realize any combination of continuous welding process, pulsation welding process and preheating welding process. Part A: The basic information Name of the machine: Updated Fixed large Flash Butt Rail & Turnout Welding Machine Model of the machineDGHG-800 Machine composition: It is mainly composed of water-cooling system, hydraulic system, welding main circuit, electrical control system, welding head, software system and other parts. Part B: Scope of application This welding machine is suitable for the processing of flash butt welding of large profiles, especially for the welding of turnouts and rails. Part C: How it works The welding machine has four independent clamping devices, which can accurately clamp the welded workpiece with irregular cross-section and keep it horizontal. The welding machine has a centering function, which can adjust the relative position of the workpiece to be welded to complete high-precision butt welding. During welding, a strong DC current is supplied to the workpiece to be welded through the clamping electrode, which effectively reduces the welding resistance. When the welding surface of the workpiece to be welded reaches a sufficient temperature, upsetting is performed to complete the welding. The upsetting mechanism can distribute the forging pressure on the welding surface to ensurethe welding accuracy. Part D: Welding range Welding of turnouts and rails conforming to the national standards of China, the standard of European Union, Russian standard, the standard of United States , etc., including the welding combination of rails and rails, rails and turnout frogs (with austenitic spacers, high-manganese steel spacers). Weldable cross section: up to 16000 mm2 Tensile Strength: 800 1300 N/mm2 Welding Efficiency: max 20 joints/hour Part E: Technical Parameters E.1 Power Requirements Power Supply voltage: 400±15V Number of phases of power supply: 3 Frequency of power supply: 50 Hz
