Features:
1.Working principle: Automatic Butt Welding Machine adopts a control system to drive the workpiece to move slowly, removing the oxide layer and irregular parts of the welding surface through flash; it then heats the workpiece ends, and finally the equipment instantly applies upset force to realize the fusion of welding ends. 2.Adopting a micro-controller to realize full-process control of clamping, flash, upset, holding and stop procedures, Flash Butt Welder delivers extremely high operating precision throughout the whole workflow. 3.Welded workpieces boast higher structural strength and better tightness, free of cold welds and air pores. Flash Butt Welding Machine ensures finished welds with solid fastness and neat appearance. Applications:
Widely applicable to metal products with uneven end faces and burrs, including tubes, bars, sheet metal and section steel made of carbon steel, alloy steel, nonferrous metals and other materials.
Advantages: 1, Machine body of thick steel sheet, not easy to deformation.
2, Fast solenoid valve, making welding speed faster, thereby the productivity is higher, therefore decreasing cost.
3, Cylinder adopt high accurate, anti-friction hard material, which is duralumin, without rust, lower friction, lower noise and loading is faster, thereby reducing the weld spatter.
4, Quality is stable, failure rate is low, therefore machine life is longer.
