Features:
As a Resistance Butt Welding Machine, it operates on the following working principle: The control system drives the workpiece to move slowly, removing oxide layers and irregular areas on the welding surface through flash trimming. Afterwards, the machine heats the workpiece ends and instantly applies upset force to fuse the welding sections together.
This Automatic Butt Welding Machine adopts a micro-controller to realize full-process control over clamping, flash trimming, upsetting, pressure holding and shutdown, delivering extremely high operating precision.
Welded workpieces boast superior strength and tight sealing. Free of cold welds and air pores, the finished joints are sturdy and neat, making the Butt Fusion Machine ideal for reliable welding results.
Applications:
It is widely applicable to metal workpieces with uneven ends and burrs, including pipes, bars, sheet metal and section steels. Compatible materials cover carbon steel, alloy steel, non-ferrous metals and more.
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.
