Compositions
This machine consists of body, right, left, up and down static and dynamic arm(all the parts casted by cast steel), electrode clamp, transverse driven upsetting device, hydraulic system, electric control system and welding transformer system. As maturely developed Automatic Butt Welding Equipment, its standardized component configuration lays a solid foundation for stable flash upset welding performance of the core Butt Welding Machine.
Features
1, Working principle: Take the workpiece to move slowly by controlling system, to clear away by flash the Oxide layer and uneven place of welding surface, then heat the ends of workpiece, the last machine give the upset force very quickly to have the welding ends to fuse.
2, Use the micro-controller to achieve complete process control in clamping, flash, upset, holding, stop.
3, Welding product's strength is higher, sealing is better, without loose-weld, without gas pore.
4, Be widely used for metal products whose ends is not flat and with burr, Tube, bar, sheet metal, section steel which materials are carbon steel, steel alloy and nonferrous metals etc.
Advantages
1, Machine body of thick steel sheet, not easy to deformation.
2, Fast solenoid valve, making welding speed faster.
3, Cylinder adopt high accurate, anti-friction hard material, which is duralumin.
4, Quality is stable, failure rate is low, therefore machine life is longer.
