High Performance Pipe Welding Machine Resistance Welding Equipment
Features:
Working principle: This
Automatic Butt Welding Machine takes the workpiece to move slowly by controlling of Gas-liquid 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.
Use the micro-controller to achieve complete process control in clamping, flash, upset, holding, stop, very high precision, making this
Butt Welding Machine deliver steady and reliable operation throughout the whole workflow.
Welding product's strength is higher, sealing is better, without loose-weld, without gas pore, fastness and beauty, which is the outstanding performance of the professional
Butt Fusion Machine.
Applications:
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.
Advantage:
Machine body of thick steel sheet, not easy to deformation
Fast solenoid valve, making welding speed faster, thereby the productivity is higher, therefore decreasing cost.
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.
Quality is stable, failure rate is low, therefore machine life is longer.
