Features
Working principle: The control system drives the workpiece to move slowly, using flash to remove the oxide layer and uneven areas on the welding surface, then heats the workpiece ends. The Resistance
Butt Welding Machine then applies a rapid upset force to fuse the welding ends together.
A micro-controller realizes full-process control of clamping, flash, upset, holding and stopping, ensuring extremely high precision.
Welded products feature higher strength, better sealing, no loose welds or porosity, with firmness and an attractive appearance.
Applications
Automatic Butt Welding Equipment is widely used for metal products with uneven and burr‑covered ends, including tubes, bars, sheet metal and section steel made of carbon steel, alloy steel, nonferrous metals and other materials.
Advantages
The machine body is made of thick steel plate, making it highly resistant to deformation.
High-speed solenoid valves increase welding speed, improve productivity and reduce production costs.
The cylinder uses high-precision anti-friction hard duralumin, which is rust-proof, low-friction, low-noise and fast-loading, thus reducing weld spatter.
Stable quality and low failure rate give this
Automatic Butt Welding Machine a long service life.
