Features
Working principle: This Automatic Butt Welding Machine uses the control system to drive the workpiece at a slow feed speed, removing the oxide layer and uneven areas on the welding surface through flash action. After heating the workpiece ends, the machine applies a rapid upset force to fully fuse the welding interfaces. The Resistance Butt Welding Machine is equipped with a micro-controller to realize full-process automatic control of clamping, flash, upset, holding and stopping, ensuring extremely high operation precision. Welded workpieces feature higher joint strength, better sealing performance, free from incomplete fusion and porosity, with firm welding quality and an aesthetically pleasing appearance.
Applications
This set of Automatic Butt Welding Equipment is widely applied to metal products with uneven ends and burrs, such as tubes, bars, sheet metal and section steel made of carbon steel, alloy steel, nonferrous metals and other materials.
Advantages
The main body of the Automatic Butt Welding Machine adopts thick steel plate structure, which features high rigidity and is not easy to deform during long-term operation.
Equipped with high-speed solenoid valves, the Resistance Butt Welding Machine enables faster welding action, effectively improving production efficiency and reducing overall production cost.
The cylinder is made of high-precision anti-friction hard duralumin material, which is rust-proof, low in friction and noise, with faster loading response, thus reducing weld spatter during operation.
Stable welding quality and low failure rate effectively extend the service life of this Automatic Butt Welding Equipment. | Model | UNS-100 | UNS-150 | UNS-200 | UNS-250 | UNS-400 | UNS-600 | UNS-800 | UNS-1000 | UNS-1250 |
