Features
Working principle: This Resistance Butt Welding Machine drives the workpiece to move slowly via the control system, flashing away the oxide layer and uneven areas on the welding surface, then heating the workpiece ends. The machine quickly applies an upset force to fuse the welding ends securely.
As a precision Automatic Butt Welding Machine, it adopts a micro-controller for full-process control covering clamping, flashing, upsetting, holding and stopping, delivering exceptional welding accuracy.
Welded joints feature higher strength, superior sealing, no loose welds or porosity, ensuring firmness and an attractive finish.
Applications
This Automatic Butt Welding Equipment is widely used for metal products with uneven ends and burrs, including tubes, bars, sheet metal and profile steel made of carbon steel, alloy steel, non-ferrous metals and more.
Advantages
The machine body is constructed with heavy-gauge steel plate, resisting deformation even under heavy-duty operation.
Equipped with high-speed solenoid valves, this Resistance Butt Welding Machine accelerates welding speed, boosts productivity and reduces production costs.
Cylinders use high-precision, anti-friction duralumin, which is rust-proof, low-friction and low-noise with faster loading, effectively minimizing weld spatter.
Stable welding quality and low failure rate extend the service life of this reliable Automatic Butt Welding Equipment.
